Fabtech 2013: On the Road to the Future in CNC Technology with Sinumerik from Siemens

Visit Siemens at Fabtech 2013, Booth S-4686

UPDATE! See the video of Siemens at FabTech HERE.

More integrated solutions needed in machine tool construction
Enhancement of CNC machining productivity and flexibility through a more highly developed Sinumerik portfolio
Sinumerik and Integrated Drive Systems (IDS): optimum added value through consistent integration across the entire life cycle

Broad-based CNC competence: Siemens will be demonstrating how productivity, flexibility and safety can be increased in CNC production with an array of smart additions to its Sinumerik portfolio

Industrial corporations are facing deep-rooted changes in the world of manufacturing. These changes are taking place alongside increasing integration of product development and production processes with the benefit of innovative software systems and high-performance software – a decisive step on the road toward a new industrial age in manufacturing. “Siemens has invested a lot of work in the integration of automation technology along the entire value chain over a period of many years, and is playing a cutting-edge role in shaping the future of production,” stated Robert Neuhauser, CEO of the Motion Control Systems Business Unit of the Siemens Drive Technologies Division, at a press conference held in the run-up to the EMO 2013. “In the Sinumerik environment in particular, and consequently in the field of CNC production in general, Siemens has been heavily involved for many years already in the area of simulation and the virtual machine, as well as the integration into factory IT systems. Our aim is to drive this process of integration forward to ensure that the field of machine tool construction is also prepared to embrace the next step in the industrial revolution,” continued Neuhauser.

Siemens Sinumerik 808D

With its Sinumerik family, Siemens offers an integral portfolio of CNC for everything from simple machine tools through standardized machine concepts to modular premium solutions, complete with “smart machine” solutions for the economical manufacture of high-end workpieces. It is working towards the consistent expansion of this CNC technology expertise. “In the future, production models will demand ever greater productivity, flexibility and efficiency, while at the same time expecting simplified machine operation and production sequences. As it continues to develop the Sinumerik CNC portfolio, Siemens is working to satisfy all these expectations,” said Joachim Zoll, Head of Machine Tool Systems Business Segment within the Motion Control Systems Business Unit. The innovations presented by Siemens at the Fabtech 2013 will consequently focus on smart function improvements, which will make for greater CNC operating convenience, increase precision at the workpiece and allow greater machining safety across every category of machine, from the compact to the high-end solution. A new function to protect against unwanted component collisions will be showcased by Siemens, for example, alongside improvements to its cohesive Sinumerik Operate user interface, including upgraded simulation options.

Siemens Sinumerik 828D Basic Family

The Sinumerik CNC portfolio is additionally playing an increasingly important role in preparing the ground for the next step in the evolution of CNC production, also within the framework of the Siemens Integrated Drive System (IDS). With a view to optimizing the addition of value across the entire process chain through consistent integration, IDS is used to integrate all the components of the drive train consistently into the complete production process environment. This also applies to Sinumerik CNC system solutions.

For every Sinumerik application, ideally coordinated system components such as high-powered Sinamics drives and Simotics motors have always been used as the ideal complements. Alongside horizontal integration of the entire drive train, with Sinumerik Integrate for Production, Siemens is also allowing vertical integration within the control architecture of industrial manufacturing automation. As the example of a leading passenger car manufacturer illustrates, this type of vertical and horizontal integration within the production process can speed up the series start for a new vehicle by up to 50 percent.

Siemens is extending its preparations for the next step in manufacturing to offer the machine tool building industry an emerging series of integrated solutions. An integrated workpiece measurement system, with a measurement accuracy of 30 nanometers deployed in the world’s biggest precision optics machine, allows the production of telescopes capable of seeing up to 13 billion light years into space

The integration across the entire product life cycle can in turn be implemented using suitable Product Lifecyle Management (PLM) software solutions from Siemens. This concept is already being implemented by leading metals processing industries such as the automotive, aerospace and medical technology sectors. This entails the increasing execution of product development and production planning onscreen, before a single machine tool has even been installed. If a modular machine is developed on a virtual basis right from the outset so that it can be fully simulated, time savings up to 40 percent can be achieved. In running operation, productivity increases of 10 percent or more are also made possible by continued simulation and optimization. At this year’s Fabtech, Siemens will be showcasing the further development of its PLM software, which encompasses scalable solutions for component production and further improved IT integration from the workpiece model through to the machine tool. Siemens will also be revealing the next stage in productivity for NC programming with the further development of its already popular PLM software, NX CAM. Going forward, this software will include special industry-specific machining functions as well as access to a new Manufacturing Resource Library.

By Bernard and Company Tags: Ad agencies, BernardandCompany, CNC, CNC machining, Industrial PR, Industrial press release, Industrie 4.0, KUKA, Machinery, Motion Control Systems, PLM, Siemens, Siemens Drive Technologies Division, Siemens Industry, Siemens Machine Tool Systems, Sinumerik, Tim Daro, Trade-shows No Comments

Dr. Robert Neuhauser (left) and Manfred Gundel (right) announce Siemens/KUKA cooperation

Siemens and KUKA held a press conference at the EMO Hannover 2013. Manfred Gundel, CEO of the KUKA Roboter GmbH, and Dr. Robert Neuhauser, CEO of the Motion Control Systems (MC) Business Unit of the Siemens Drive Technologies Division, has informed about an enhanced cooperation.

· Joint solutions offered: integrated, operator-friendly loading of machine tools using robots
· Integration of robotics and CNC solutions for machining workpieces with robots
· Strengthening the fundamental idea of integrated production processes
· Development of new applications in lightweight construction

Siemens Drive Technologies Division and KUKA Roboter GmbH have announced comprehensive cooperation at EMO in Hanover. The central pillar of the cooperation is integration of KUKA robots and Siemens CNC solutions for loading machine tools. “With this joint approach, the two companies are strengthening the fundamental idea of integrated production and can, for example, develop new markets by close intermeshing of machine tool tasks and loading tasks,” says Manfred Gundel, CEO of KUKA Roboter GmbH. “The CNC control from Siemens and the robot controls from KUKA are ideal for integrating robot and CNC technology. With this cooperation, we are deepening our many years of cooperation and together advancing intelligent automation solutions as outlined by the Industrie 4.0 project for the benefit of both partners and to expand business,” says Dr. Robert Neuhauser, CEO of Business Unit Motion Control Systems at Siemens.

Highly flexible and fully automated production today demands complete integration of robots into the production flow and into the automation environment. In this area, in particular, applications for robots and machine tools are growing together steadily as a result of new requirements and technological progress. Given these developments, Siemens and KUKA are strengthening their cooperation in automation and industrial robots. The aim is to be better able to serve industries with high automation requirements in loading and machining. With the shared development, customers will have access to new products and solutions that are coordinated optimally over their entire life cycle, from design, to production simulation, to engineering and the production shop level. Moreover, in the long term, the two companies will be including aspects of robot automation in their activities as outlined in the Industrie 4.0 project.

With this close partnership, Siemens and KUKA can offer end customers integrated solutions with a high technological demand and level of maturity and position themselves still better on global markets. At the center of the joint development and the closely meshed marketing activities is seamless, operator-friendly integration of the robot for loading the machine tool. The companies will also develop scalable, integrated solutions for machining workpieces with robots, especially for lightweight construction. In this field, in particular, new materials such as composites require innovative machining concepts that the two companies will be intensively advancing as part of the cooperation.

KUKA will provide robot systems that make use of proven solutions in the field of CNC with Sinumerik from Siemens for integration with machine tools. The standard implementation of the concept includes loading by a KUKA robot, which is integrated in Sinumerik. A scaled offer is also planned ranging from a robot with additional CNC machining functionality to a robot as a pure CNC machining unit. Here, too, the aim is complete integration of the robot into the PLM processes.

At EMO 2011, both partners have already presented the integration of the robot into the Sinumerik user interface as an application, for programming, teach-in, and diagnostics. The next step will now be the connection to CNC tasks.

A Lesson in Machine Tool Economics

By Bernard and Company Tags: Ad agencies, CNC, Inc., INDEX C100, Industrial PR, Press Release, Siemens Industry, Siemens Machine Tool Systems, Sinumerik 840D, Task Force Tips, TFT, Tim Daro No Comments

When Task Force Tips, Inc. (TFT) decided to study the true costs of ultra-priced, high-speed machining, the company expected nominal gains on its machine-control investment; but when TFT began cutting the same precision parts in one-third of the time, it was, in the words of the company owner and president, Stewart McMillan, “a wake-up call.”

See the video on this story HERE.

Breaking the price/cost perception barrier

Task Force Tips (TFT) is a manufacturer of highly engineered fire suppression tips, nozzles and other agent delivery equipment used by fire departments globally. For more than four decades, the company has always invested in premium machine tool brands associated with quality, performance and logically, higher price tags. Even so, it was the latter variable – the perceived barrier of price and cost – that prevented company owner and president, Stewart McMillan from ever considering more ultra-priced, high-speed machining options on the market.

“I hadn’t really looked at the economics when it came to an INDEX machine,” recalls McMillan. “And why? Because it always seemed like the INDEX brand was so prohibitively expensive. I never even thought its machines were within our league.”

That was prior to IMTS 2008, before TFT brought the company’s first INDEX machine into its 168,000 square foot facility in Valparaiso, Indiana, where TFT manufactures over 5,000 products across three shifts, seven days a week, all year around.

The Index C100’s “literal” coordinate system establishes actual reference points for programming the machine’s precise motion, rather than use arbitrary points in space.

“It was an INDEX C100 automatic production lathe, ultimately fitted with a Siemens 840D control package,” McMillan says. “We started making parts on it and our production times became typically 30%. I don’t mean a 30% reduction. I mean our run time for a part dropped to 30% of what it was before.”

As to why the company’s new machine made such an unprecedented productivity impact, McMillan points to both the high speed design of the machine and to the equally capable Siemens control package, which represented yet another paradigm shift for TFT.

Previous to the INDEX C100 purchase, TFT had scant experience with Siemens control packages. Much like the INDEX brand, Siemens five-axis controls were perceived as prohibitively sophisticated and just plain different. This lack of familiarity had been reason enough for TFT not to consider Siemens.

These were the company’s perceptions in 2008, before the INDEX C100 machine came into the plant, powered not by a Siemens control package, but by a more commonly accepted brand of CNC.

“We had all kinds of bugs in the control that came with the machine the first time,” McMillan recalls. “INDEX had a particular customer that had insisted on another more familiar brand of control, and so they were making the machine with that control. I don’t think that the other customer realized just how significant the Siemens control was to the machine. We didn’t recognize it either. A service representative commented to one of my employees that we really should have the Siemens control for what we were doing, that we were pushing the machine far beyond the capabilities of the original control.”

Upon learning that its new machine was underperforming for TFT, McMillan says INDEX swapped out the machine with an identical model, with one difference. This time, the INDEX C100 was powered by a Siemens motion control package, and TFT was able to set out in earnest to explore what price/cost lessons could be learned from its machine tool investment.

Zero to 5,000 RPM in one second

The INDEX C100 features automated remnant removal. The design has helped TFT increase revenues by eliminating the production delays caused by manual remnant stock removal cycles– typically not an option on lower priced machines.

McMillan recalls that an immediate revelation was seeing the difference a few thousand RPMs can make. The company began to run jobs at 5,000 to 6,000 RPM, ramping up from zero to 5,000 RPM in less than one second and ramping down just as fast. Several economic lessons soon emerged from this capability, as the sustained speed of the machine maximized motion in new time/cost saving ways.

“We never realized before just how much time we were losing waiting on the spindle to stabilize at a new commanded speed,” McMillan reports. “The turret indexing was also extremely fast, with the multiple tools overlapping to cut at the same time with incredibly fast accelerations.”

The INDEX C100 also leverages speed in new ways, as TFT discovered. The company can run more than 1,000 parts without having to change an offset. In addition, an automated remnant removal feature enables the machine to run continuously, by rapidly reloading bar stock without operator interaction.

“On the rest of our machines, we need to pick the remnant out and load a new bar into it,” McMillan explains. “That step should take just a few minutes. But the way things work, a machine can sit idle for six minutes before somebody realizes it, and then it takes five minutes to reload, and all that lost time adds up.”

Another speed-related discovery was the integration of rapid traverse rates, which have always been less than rapid in the company’s experience “A lot of machines advertise rapid traverse rates at maximum speed, but the fact is, unless you’re traveling 10 or 12 inches, traverse speeds have never reached maximum for us.”

Taking motion accuracy literally

As to how the machine eliminates slower traversing and other cost related functions, McMillan says the design of the INDEX C100 is unlike the design of conventional and yes, lower-priced machine bed coordinate systems.

“The INDEX doesn’t use the same coordinate system as other machines. It uses a set of parallelogram bars, a very unique system for rigidity,” McMillan explains. “The machine has a picture frame mount for its turret. The turret is not leveraged off a set of ways like most turrets. It’s close to where it’s sliding, so there’s not a big length over diameter ratio in terms of the tools of the turret hanging out from its support structure. This gives the machine a lot of rigidity for turning, and you can accelerate the axes so fast that you really do achieve faster traverse rates. The window on this machine is just a blur of motion.”

The coordinate system of the INDEX C100 uses a set of parallelogram bars for uniquely rigid motion that is fully exploited by the Siemens SINUMERIK 840D.

TFT’s lead programmer, Nate Price, sees additional efficiency advantages made possible by the INDEX machine’s unique coordinate system, whereby measurements and motion can be programmed based on actual numerical reference points and not on arbitrary points in space.

“On the INDEX, every machine space coordinate, every offset, every measurement that’s used to define how the machine operates has a legitimate explanation of why it is what it is and to where it relates,” Price explains. “This makes it much easier to automate these measurements; whereas, in the past we would measure manually, because these were arbitrary points. On the INDEX, they are defined, literal points. We know exactly what they relate to, so we can define them automatically before the program ever gets to the machine, before the set-up ever starts.”

Advanced cost control

With the Siemens 840D control package driving the INDEX C100, TFT would document yet more lessons in machine tool economics, including reduced setup times. The faster indexing speed of the turrets contributed to an 80% reduction in setup times compared to the setup times of TFT’s other premium machines.

According to Price, the Siemens 840D control interface brought a refined and intuitive approach to machine programming, setups and operation — an approach that was especially empowering to him as a programmer.

“I don’t know if anybody just doing set-ups would understand how much of a difference the Siemens control has made in the programming,” Price explains. “It has enabled me to more quickly and easily write the programs, write the post-processes, thus making the setup of special routines go much faster.”

In addition to easier programming and faster setups, Price says the machinists have found that the Siemens 840D enables them to more efficiently control and capitalize on the production potential of the INDEX machine.

“The control gives you ample shortcuts,” says Price. “There is a method of presenting messages to the operator that was not present in the other control. There is so much happening on the machine, it is really difficult to capture all that information on a single screen, but the control helps you keep track of what everything is doing. It’s really easy to get into more detail, without having to go through a lot of pages.”

As another example of CNC operational efficiency, Price points to the way the control manages error messages.

“The machine wants to see several conditions exist before it will start a cycle,” Price explains. ”On the previous control, it was not real good at telling you that it was not in a condition to start a cycle. It wants the chucks closed. It wants the gantry in safe position. It wants the sub-spindle in a safe position. It wants to know where everything’s at and it presents a giant list for the operator to reference in order to start a cycle on the machine. But, when you press Cycle Start on the Siemens control, if those conditions aren’t met, the control will guide you through what needs to change to meet those conditions, so you can start your cycle.”

Another advantage brought about by the Siemens control was faster tool loading, made possible by faster and easier CNC programming.

“Tool loading was a big area of improvement,” Price says. “You essentially give the control a mini-program that tells it what tools you’re going to be putting in for this job that you’re setting up. The control will then present the stations on the turrets for you, tell you what tools to put in and what tools to take out. And it’s entirely guided. This has been a huge departure from what we traditionally had dealt with. It really accelerates set-up time.”

More profit per square foot

McMillan and Price claim that the lessons derived from their machine-tool investment can be measured in broader and perhaps even more dramatic ways.

“I started to look at the numbers from a different perspective,” McMillan relates. “You have all these initial and ongoing costs to build a shop, to put in a floor, to put a roof over it, heat it, cool it, and all these costs can equate to so much per hour. Now you buy a machine that’s $600,000 versus a machine that’s $300,000 over 10 years. We run almost 24 hours a day, seven days a week, which helps our analysis. For us, it comes out to about an eight dollar per hour difference to buy the $600,000 machine. And for eight bucks more an hour, we’re getting triple the production out of that same square footage.”

Another way the company has measured its return on its investment in advanced machine-control manufacturing has been to witness the change in the people uplifted by the technology. Now, owner, programmer, machinists and others at TFT are enthusiastic about the possibilities of their more advanced, CNC-based manufacturing.

McMillan says that it will be such investments in machines and in people that will keep his company from selling itself short, having proven that with the right machine and the right motion control technology, anything is possible.

“We had a job that ran a couple of weeks ago,” McMillan recalls. “I received several e-mails before I even came to work that day. Different people were sending me e-mails that said in effect: Wait until you see what we’re doing with the INDEX today!”

Siemens to Demonstrate Kuka Robotics Integration for Workpiece Handling

By Bernard and Company Tags: Bernard & Company, CNC, IMTS, Siemens, Siemens CNC, Siemens Industry, Siemens Machine Tool Systems, SINUMERIK 840D sl No Comments

All motion controlled by mxAutomation directly through the Sinumerik CNC — simple to integrate, even easier to operate

CHICAGO — At this year’s International Manufacturing Technology Show (IMTS) in Chicago, Siemens will demonstrate its recent collaboration with KUKA Robotics. In the Siemens booth E-5010, a KUKA robot will be articulating parts, simulating the operation on a CNC machine tool. Key to this development is the machine builder’s ability to integrate mxAutomation from KUKA directly through the Siemens Sinumerik CNC platform, thereby allowing the operator of the machine to run both the machine tool and robot from the single control panel.

The motion sequence of the robot is entirely engineered within the Sinumerik 840D sl CNC, then transferred by the 840D sl’s PLC function to the mxAutomation interpreter on the KR C4. All program changes to a six-axis robot can easily be input on a second channel of the CNC and fully operated. This scenario provides the ability to not only run a machine tool’s automation sequence more efficiently, but also make more changes on-the-fly to minimize machine downtime, with no special knowledge of robot programming language.

During the operation of the machine tool, all changes made can be visualized directly on the CNC screen, further minimizing operator actions. Siemens is the first CNC supplier to show this capability for single-screen operation of the machine tool and robotic materials handling on the CNC. During the show, a Siemens Sinumerik 840D sl CNC will be programmed to allow the operator to jog the robot, command the gripper and otherwise simulate integrated actions with a machine tool.

In operation, the KRC4 integrator and mxAutomation convert the robot language into the same commands used for multi-axis machine tool functions. A single Profinet cable runs between the robot and the CNC. According to KUKA’s Andreas Schuhbauer, key technology manager for machine tool automation (Augsburg, Germany), “mxAutomation allows the machine tool builder a single I/O language for integrating robotics on the CNC, while the end user operator can run both the machine tool and the robot from a single screen on the control.” mxAutomation for Sinumerik CNC was a joint development between KUKA and Siemens. KUKA created plug-in function modules for the Siemens Step 7 PLC engineering software and provided its robot knowledge to Siemens for creation of the second channel logic on the CNC, Andreas Schuhbauer further noted. All safety functions and test functions for load / unload, brake test, gripper, robot communication and safe operation of the robot are provided through the Siemens Profinet and Profisafe platforms.

Future developments for mxAutomation are planned, including a wider application range for robots in the CNC machine tool environment. For more information about Siemens CNC solutions for the machine tool industry, visit our website: www.usa.siemens.com/cnc.

Integrated Sawing and Machining Center Sets New Industry Standard

By Bernard and Company Tags: ACS Sawing Machine, Ad agencies, BernardandCompany, CFMcurve, CNC, IMTS 2012, Industrial PR, machining, Rattunde, Rattunde Corporation, sawing, Tim Daro No Comments

IMTS PRE-SHOW NEWS…BOOTH N-6737

Rattunde Corporation introduces the ACS + CFMcurve integrated sawing and machining center, an exciting new technology, at the IMTS show, McCormick Place in Chicago, from September 10-15, in the North Hall Booth #6737. A fully operational system will be producing a variety of parts, demonstrating the fully automated flexibility of this manufacturing center.

The ACS Sawing Machine is the new industry standard for cold saws. It utilizes a proprietary sawing algorithm with servo motor controlled feed to continuously adjust critical sawing parameters during each cut. The results are the fastest sawing times, best surface finish and longest blade life available on the market.

The CFMcurve machining center is a patented Rattunde process that simultaneously machines each workpiece end, using 12 independent servo-controlled axes. Machining options include: threading, boring, profile turning, grooving, radius edges and angled chamfering. Programming screens guide operators for quick setup on even the most complex part geometry. No special programming is required.

Precision parts are made in one continuous process with no operator intervention. Bundles of mill length stock, up to 16.5 meters (54’) long, are placed in an automatic loader, individually separated and fed to the sawing process. Cut parts are then transferred to the CFMcurve machine for precise finishing. Utilizing advanced CNC controls, linear ball screws and servo motors, all mechanical motion is seamlessly integrated into the machine design for full process control.

The technology incorporated on this manufacturing center delivers production rates and quality unmatched by the competition. For example, a tubular component of 70mm diameter, wall thickness of 5mm, material type ST52-3 BK, with a length of 150mm, machined with a 30 degree chamfer on the ID & OD with a faced end has a saw time of .96 seconds, a machined time of 1.86 seconds and the machine can produce 1,820 parts per hour, inspected for length and automatically packaged. Cut length tolerance of +/- 0.15mm at 1.67 CPK and a machined length tolerance of +/- 0.05mm at 1.67 CPK are maintained with consistency.

The operator interface saves part files for instant recall when changing parts. Servo motors move all cutting and machining tools to their exact positions and implement saved parameters. No tooling change is required in the ACS Saw within a diameter range of 10mm; there is a 5mm diameter range in the CFMcurve. Tooling change for the complete system takes less than 20 minutes, when necessary.

All critical sawing and machining parameters are monitored and controlled. Clamping forces and position, saw blade torque and vibration, plus machining insert torque are continuously displayed and monitored. Operating limits are set and machine functions stop when they are not met. Saw blade and tooling insert wear is predictable and consistent. Key data for each part produced are stored in memory for statistical evaluation. All guesswork is removed for the operator.

Rattunde sets a new industry standard for manufacturing with this machine, replacing slow and unreliable processes with a complete manufacturing center. Bar feeding lathe machines rely on a slow cutoff process, restrict the length of incoming stock and are not always capable of finishing both part ends simultaneously. Cutting in a conventional saw, dropping parts in a bin and eventually loading them to a conventional machining center is time consuming, labor intensive and creates excess inventory with a loss of process control.

Additional processes, engineered and manufactured by Rattunde, are easily integrated with the ACS + CFMcurve, including: part inspection stations, washing and drying, automatic packaging and automatic container changing, all available to further automate customer manufacturing. The system being exhibited at IMTS will include part inspection and automatic packaging.

Through the use of Siemens SINUMERIK CNC technology, plus PLC and HMI, on a combination servo-controlled cold saw cut-to-length and brush deburring system, Rattunde customer achieves triple the output on small engine exhaust components

Rattunde ACS + BDM tube and bar production system at Cosmos.

Rattunde Corporation of Grand Rapids, Michigan is the five-year-old subsidiary of Germany’s Rattunde & Co. GmbH, a machine tool builder of tube, pipe and bar processing equipment. The company is already making its mark in the American manufacturing industry, as demonstrated by a recent success it had at Cosmos Manufacturing of South Chicago Heights, Illinois, a major supplier of small engine exhaust tubes to the leading outdoor power equipment manufacturers in the country.

The Rattunde system, incorporating a servo-controlled cutoff saw and brush deburring mechanism, is consistently producing up to 11,000 parts per hour at Cosmos, according to Mike Jemilo, the end user’s general manager. “This number represents triple the output production for Cosmos.” He continues, “Better still, it’s been in operation more than a year and we have not reported a single reject, with only routine maintenance and zero downtime due to machine problems. This is truly a win-win scenario for the machine tool builder and us alike.”

At the heart of the Rattunde system, according to Richard Stadler, company president, is the computer numerical control (CNC) system used by this builder. It consists of a Sinumerik 840D CNC, Simatic S7 PLC with various analog and Profibus modules, plus numerous Simotics servomotors, motor protection devices, circuit breakers and other components supplied by Siemens.

Machine performs all servo-controlled saw cut-to-length, washdown, brush deburring and packing operations on a single line, controlled by Siemens CNC and HMI.

At Cosmos, this Rattunde system is used to process mill-length tubes to customer-specified dimensions, using a fully NC-controlled cold saw. Cut-to-length parts are then automatically measured for dimensional accuracy and brush deburred. Production of these parts runs up to 11,000 units per hour, according to Cosmos’ Mike Jemilo. Because of the overall improvements in automation, speed and parts handling, plus the precision of the Sinumerik CNC system, Cosmos is further experiencing significant reductions in parts handling, secondary operations and final assembly.

The primary products being produced on this equipment at Cosmos include mountings, connectors and sections for muffler tubes in dozens of lengths, typically in 3/8-inch, 7/16-inch, 12 millimeter and 1/2-inch sizes. Products are routinely run in mild steel, aluminized steel and stainless steel on the same Rattunde system, with offline pre-programming done by the Cosmos engineering team. The final products are sold by Cosmos to leading manufacturers of chain saws, leaf blowers, lawn mowers and other small engine-powered equipment.

All machine functions and 13 axes of movement are affected by the Siemens CNC, which also provides remote monitoring capability for the builder Rattunde.

Jemilo concluded by citing the Rattunde service advantages. “From the initial contacts with their application engineering, through the build process, commissioning and on-site training, we’ve been extremely impressed with their work — very professional and responsive. Our previous system had nowhere near the production of the Rattunde solution and we are already working with this supplier on our next system.”

From the machine tool builder’s perspective, the same relationship is echoed about Siemens. Alec Banish, vice-president at Rattunde, commented, “We were asking Siemens to do some fairly complex operations in motion control, including 13 total axes with an articulating gearbox, plus the conveyor and part articulations, spindles and servomotors.” He further noted the scalloped motion of the ID/OD brushing with disc transfers all presented unique motion challenges for the control hardware and software alike. “The Siemens servo technology automated our entire process in a totally controlled, high-precision manner, allowing customers such as Cosmos to process a wide variety of materials, dimensions, shapes and lengths with easy-to-manage presets.” Banish concluded by saying, “The Siemens support is greatly enhanced by the remote monitoring capability of the Sinumerik CNC. About 70 percent of our issues are resolved remotely, working between us and Siemens or directly with the customer’s plant personnel.”

Prior to the implementation of the Rattunde system, all the piece part work done at Cosmos required two or three saws, with the attendant fixturing, parts handling, logistics and labor costs. These bottlenecks in production were eliminated by the fully automated and single operation processing of the tubes provided by the Rattunde system. Four tubes are processed per cycle, with servo control of the entire bundle, as it moves through the saw, brush and loading zones on this fully integrated machine line.

Rattunde builds various production systems for tube and bar product manufacturers.

From a factory utilization perspective, the prior system at Cosmos ran in three shifts for six days, each week. Today, with the Rattunde system on the floor, occupying a far smaller footprint, one shift per day working just five days produces the same output with far superior quality and virtually no rework, according to company sources.

Rattunde President Richard Stadler further comments on the power of the Siemens CNC and related motion control products. “We’re using all ten channels and pushing the axis capability to some extreme limits, but have seen absolutely no problems in signal degradation or processing speeds.” Stadler also observed the Sinumerik CNC program storage capabilities were quite impressive. “All the operator needs to do is provide a size range indication onscreen and all the relevant programs appear for easy selection. Repeatability is obviously critical for our customer, who often process dozens of shapes and sizes per shift.”

He recalled meeting the Cosmos team at FABTECH in 2009. “They approached us with their scenario and it was right in our wheelhouse. We did some test cuts and time/motion studies for them and the results were quite impressive, both to them and to us,” Stadler muses.

Rattunde operates facilities in Grand Rapids, Michigan as well as a service center in Burlington, Ontario to better serve their North American customer base.

Rattunde markets its tube and bar production systems to makers of precision parts. Currently selling 60 percent automotive, the company’s systems produce airbag canisters, cam shaft cylinders, steering components, rack mounts, driveshafts, frame components, seating parts, headrests, shock absorber parts, door impact devices, luggage racks and a variety of axles. In addition to the cut-off and brush deburring system detailed here, the company also supplies production systems to perform various types of secondary machining operations, including threading, facing, chamfering and ID turning.

EMAG Uses The Same CNC and Remote Monitoring On Various Machine Tools Sold to Major Agriculture Equipment Builder

By Bernard and Company Tags: Ad agencies, BernardandCompany, CNC, emag, Industrial PR, Industrial press release, Machinery, remote monitoring, Siemens, Siemens Industry, Siemens Machine Tool Systems, Sinumerik 840D, Tim Daro No Comments

Siemens Sinumerik 840D is the control of choice on turning, grinding and turn/grind models, resulting in substantial savings for its customer and EMAG

EMAG L.L.C. is the U.S. subsidiary of a major German machine tool builder who specializes in machine tools for the production of automotive, off-highway, agricultural and oil field components. The company’s equipment ranges from basic prismatic part turning centers to large workpiece, five-axis machining centers, gear hobbing machines and alternative cutting equipment such as lasers and electro-chemical machining centers. This wide variety of machine tools requires an assortment of control technologies to power and manage the motion. For one recent customer requirement, where a major agricultural equipment builder in Iowa needed grinding, turning and turn-grind machines, EMAG looked to its longtime partner Siemens for a standardized CNC solution.

CEO Peter Loetzner put it simply, “We needed to devise a control solution that would satisfy all the needs of the various machines we were supplying to this demanding customer, based on a common platform, to enable easier design, integration, start-up, commissioning on-site and training for our customer’s operations and maintenance personnel.” After reviewing the entire line of CNC offerings from various suppliers, the decision was made to use the Siemens Sinumerik 840D CNC for all of the grinding, turning and turn-grind machines to be supplied. Collaboration was a key element in the decision-making process, as Loetzner explains.

“The control we selected offered great flexibility in application, which was very important to us and our customer. They were seeking a scenario that would allow considerable cross-training of their operators, who might run a turning center one day, then a grinding or turn-grind center the next.” Loetzner further noted the control chosen offered his machine designers and the customer’s production management team an enhanced remote monitoring feature, so changes could be made on the fly with very little downtime. As a result, over 20 machines of various sizes and styles can be monitored over a wireless network, enabling process engineers to see what the operator sees on each machine.

Furthermore, owing to the global capabilities of Siemens, Loetzner commented on the control’s ability to function

in U.S., German and even Asian factories with seamless data integration. Regardless of the machine tool’s location, EMAG and its customer are able to monitor the performance of any particular machine and even report comparative production data from one continent to another. Because it sells into every industrialized nation, EMAG “…works with its customers on every aspect of a job, from the order process to tooling usage, materials handling strategies to predictive maintenance. The cultural differences are substantial sometimes and the control must be programmed to adapt to such variations. We have been most satisfied with the help Siemens has provided to us, worldwide, in this area.”

Those differences, he continued, must nonetheless be based on a common technology to streamline the integration of the CNC on the machines under construction.

Loetzner cited specifics from the project referenced in this story. “We were looking at a fairly diverse group of machines being supplied to the customer. Frankly, many of their operators were more comfortable with a CNC that is very popular in the American job shop community. However, we were able to demonstrate the immediate advantages of the Siemens control to them and they accepted our recommendations.” This value proposition, he said, hinged on the greater capability of the Sinumerik 840D to run different machine types, which translated into considerable savings on the training and commissioning side of the equation. Coupled with the remote monitoring and programming aspects of the Siemens control solution, the customer was convinced.

Production VSC from EMAG is a vertical pick-up turning center capable of milling, turning, grinding, drilling, even gear profiling and honing.

More than 75 percent of the EMAG machines at this particular customer are equipped with robotic devices, enabling a lights-out manufacturing scenario, another instance where the Siemens remote monitoring via Ethernet feature benefits both the machine tool builder and its customer alike. Loetzner explains, “Remote monitoring of the machine tools can be done directly through the Sinumerik CNC in a one-to-one exchange between our customer and us. Alternatively, we can communicate with Siemens and our customer in a three-way exchange of machine data and cycle information, all protected through a firewall for security and customer peace-of-mind. That’s important with all our major OEMs, of course.” Loetzner cited one customer in the agricultural machine building market, who’s used the remote monitoring capability of the Sinumerik CNC on a wide variety of EMAG machines for over three years currently, with all data communicated through a single information network, accessible by both EMAG and the control supplier. Significant reductions in downtime, service calls and troubleshooting identification time have been achieved, translating into documented savings for everyone.

Shaft machining is done on a VTC, with full 4-axis machining plus loading and unloading, all controlled by a Siemens CNC.

As a further advantage to the machine tool builder, the space reduction of more than 20 percent in the control, compared to competitive brands, meant a smaller footprint for the machine, further improving the workspace productivity of the EMAG machines for their customer. Especially in brownfield applications, where a limited space is being utilized to maximize production for an OEM, this physical space-savings combines with other advantages of the Siemens control, according to Peter Loetzner. These include reduced wiring and lower power consumption with the attendant lower operating temperatures, due to reduced ambient heat.

At this particular customer, the EMAG machines are used to produce gears, gear blanks, shafts and splines for

powertrain applications. Gear hobbing and synchronous support grinding are among the advanced machining technologies performed here. Heavy, hardened steels are the most often worked substrates.

The specific control used on these machines is the Siemens Sinumerik 840D solution line, a distributed, scalable and open control for up to 31 axes of motion, incorporating the CNC, HMI, PLC, closed loop control and communications functions into a single NC unit. Sinumerik Safety Integrated further provides a comprehensive, yet efficiently packaged suite of personnel and machine protection functions, fully compliant with internationally-accepted standards.

Commenting on the competing brands of CNC often found in job shops worldwide, Loetzner noted that the Siemens communication architecture easily accepts input from such devices, owing to its ability to capture, standardize and transmit all data in a seamless manner through its legacy tracking. “This service is another example of a forward-thinking supplier, such as Siemens, responding to brownfield conditions in the marketplace,” he noted.

EMAG machines are used by the majority of American companies for the production of such products in the Agriculture, Earthmoving, Motorcycle and Automotive and subsequent leading TIER1 suppliers. The machine builder has had a presence in the American market for over 20 years and, according to Peter Loetzner, “…we’ve received great support from Siemens, both in Germany and in the United States, for on-site service, application engineering, parts distribution, remote monitoring implementation and communications between our customers and us.”
