Over 100 axes of motion can be engaged on system architecture
Siemens Industry, Inc. announced today the availability of a Simotion Synchronized Drive Control (SDC) standard application solution as a complete package for immediate implementation by machine builders, system integrators and end-users alike, in printing and converting applications. As mechanical line shafts decline in their use and are being replaced by electronic line shafts, torsion elasticity and gear backlash are being eliminated where the printing press or post-press machine sections electronically gear the individual sections together. Utilizing Virtual Master technology ensures perfect synchronism between machine sections. Axes on a single or multiple Simotion controller arrangement can be geared together in a common Virtual Master, then operated in a Global Master mode when all axes are in operation, or a Local Master, when only sections of the line are running. Operation with multiple Global Master and Local Master modes is also possible.
To maximize the make-ready and uptime efficiencies of the line, it is often necessary to electronically decouple line sections for plate changes on the fly. With today’s drives, drive controls and electronic feedback devices, in addition to this Siemens solution suite, it is now possible to synchronize all drive sections to streamline the process.
Synchronized Drive Control is a ready-to-use solution dedicated to the synchronization of all motion functions, whether local or synchronous. It can be implemented in minutes and includes comprehensive documentation. As an open source application, Simotion SDC is immediately customizable for the printing line or converting machine’s specific requirements. Integrated WinCC Flexible HMI is ready-to-use during development, commissioning and operation of the line, as well.
Simotion SDC can synchronize all motion functionality between multiple Simotion motion controllers over a Profinet network, allowing 100+ axes to be engaged on the system architecture simultaneously or grouped, as needed.
This solution can be applied to gravure, offset, flexo and digital printing presses in wide, mid-range and narrow web format, as well as a broad range of finishing equipment including binders, stitchers, inserters, collators, polywraps, conveyors, grippers and stackers. Simotion SDC is further complemented by the Siemens Converting Toolbox for use on a full range of winding, web transport and tension management systems.

To guarantee perfect workmanship and the highest possible product quality, BMW uses five-axis machining centers equipped with Sinumerik 840D sl and a range of new user interfaces for machining operations in its Berlin motorcycle plant.
BMW motorcycles enjoy an outstanding reputation around the world for their reliability, quality, performance and safety. This is not achieved by chance, however. BMW’s motorcycle plant in Berlin uses around 50 machine tools to create numerous key components on-site, from frames and valve shafts to connecting rods and cylinder heads. Among these tools are Grob’s horizontal five-axis G550 machining centers equipped with Sinumerik 840D controllers, which are used in the manufacture of cylinder heads for flat and 4-cylinder engines. Prices are obtained from suppliers at regular intervals, especially when the company is investing in new machining centers. The aim is to ensure that BMW can manufacture its components more cost-effectively than external contractors, while at the same time comparing the prices offered by the various machine suppliers. One of the major reasons for choosing the G550 was because it was equipped with a Siemens CNC.
The horizontal design of the Grob five-axis G550 guarantees the highest levels of rigidity, which keeps axial deviations below 10 µm.
Thanks to previous positive experience with Siemens, the BMW manufacturing specialists in Berlin already employ technology from Europe’s market leader for 90 percent of their controllers. This allows both operators and tool setters the flexibility to work on almost all the machines in the plant. Other key requirements noted in the specification were adequate space for manufacturing all relevant components, the highest levels of precision and surface finish, compliance with pre-defined cycle times, and the ability to reuse all current tools and equipment.
The highest levels of precision on even the hardest material
Before committing to the new investment, the responsible BMW production engineer worked with a colleague from process engineering to investigate the effectiveness of the Grob machines in cylinder head production. Initially, it was the G550’s near-identical sibling, the G350, that was under consideration. As a first traditional single-workplace machine tool, it already met almost all the main criteria, but the space available inside was deemed too small to accommodate all the required processing tasks. However, the G550 satisfied this requirement as well. Among other factors, the horizontal design of this five-axis machine, which has both rotary axes in the work area, contributes significantly to its outstanding rigidity. As a result, axial deviation remains process-compliant at values under 10 µm. The level of precision that can be achieved is correspondingly high, even when processing extremely hard materials, as with valve seat inserts, for example.
The machine also produces a high-quality surface finish, with roughness (Rz) of up to 2 µm. Christian Heiß, applications engineer at Grob, explains a further benefit of the horizontal design: “Tool life can be increased by approximately 30 percent compared with that of vertical machining centers. And the problem of jammed slivers is almost completely eliminated because they are not able to fall onto the workpiece in the first place, but instead fall right through to the ground.”
One of the G550’s strengths is its compact size, at only 3800 mm x 6300 mm. However, despite its size, it still features an extremely long z-axis stroke of 1020 mm, meaning that tools up to 500 mm long can be retracted completely out of the work area and into the so-called spindle tunnel. The swivel-mounted shuttle table is another feature that helps deliver high levels of productivity. While one workpiece is being processed, the next can be clamped and set, thus minimizing costly downtime. 
Programmed and set in no time at all
Employees find the new Sinumerik 840D sl CNC especially easy to operate because, in the production of BMW cylinder heads, only Siemens controllers are used. Despite this, the user interface presented on the Grob machines looks completely different from the others. Until now, operators and setters have been used to the DIN-based HMI Advanced user interface, but the new CNC on the G550 features the Sinumerik Operate animated graphical display. Siemens has integrated a new operation and programming structure, with practical functions such as copy and paste that are well known to users from their daily use of PCs. This allowed BMW employees to quickly adapt and master the new Sinumerik user interface in no time at all.
Thanks to its excellent usability and intuitive operation through various technology cycles, measurement cycles, and setting functionality, the new G550 machines can be set up for new batches much more quickly than before. As Heiß explains: “This means our customers are much faster than before. Previously, it might have taken several hours to set up the machine and the workpiece, now it can be done in just a few minutes.”
Highly trained employees and specialist suppliers help BMW motorcycles maintain their excellent reputation for reliability, quality, and safety.
Quick and reliable with remote maintenance
Along with the tools and equipment from the current machines, the German motorcycle manufacturer was able to reuse all its existing programs as well. It took a single employee only two days to upgrade these programs to be compatible with the latest software, which can be loaded onto the relevant machine as required either over the network or from a USB stick. The modern Windows Explorer-style program manager means that complex programs can be managed either on the CF (Compact Flash) card or directly on the CNC.
If problems arise while the machine is operational, BMW production engineer Taner Ögretmen and his colleagues use the network-based remote maintenance functionality provided by Grob. This has rarely been required so far – but when it has, it proved to be extremely smooth and efficient, stresses Ögretmen. Grob can also perform minor optimizations together with Siemens using the teleservice. This is usually done automatically and without any disruption to ongoing production. The Sinumerik-controlled Grob machines have met every expectation in full, which is why BMW has already ordered an additional four G550s.
Programming and operation using Sinumerik Operate
Sinumerik Operate provides several different programming methods to let users program and set the workpieces: ShopMill graphical user interface, programGUIDE for G-code with cycle support, and pure DIN/ISO programming. If the user decides to use ShopMill, he or she receives an animated graphical work-step programming environment for simple dialog programming. The interface is designed to
be clear and self-explanatory, so that even operators with no programming experience can learn the basics in no time at all. To write programs in programGUIDE, the operator will need some knowledge of G-code. The highlights here include new cycle support functionality and animated elements that can be used to represent the cycle graphically. Tooltip support is also provided.

The art of organ building at the highest level with modern CNC techniques…
Laukhuff relies on five-axis milling center from Spinner with Sinumerik 840D sl for small-series production
Walter Rhein, Manager of Cutting Applications at Laukhuff
At Laukhuff in Weikersheim, Germany, tradition and modernity merge together in a way that can not merely be seen, but also heard. The family-run company, with almost 200 years of history, is the international leader in organ building – as a supplier to the best-known organ builders and a provider of its own complete instrument developments. The company operates on a global level with 150 employees, considering itself an artistic crafting enterprise rather than an industrial company. Company CEO Hans-Erich Laukhuff emphasizes, “In our carpenter’s workshop and when manufacturing organ pipes, we are hardly able to use any machines because 90 percent of the work must be done by hand. When it comes to cutting, however, this is a different matter. Here, we can use modern milling and turning machines with innovative CNC equipment, so that we can keep productivity levels as high as possible.”
Walter Rhein is very satisfied with the five-axis Spinner U5-620 with Sinumerik 840D sl
If required, these masters of organ building will supply everything from a single source. Laukhff further explains, “If requested, we will take on all the tasks involved in the design, the manufacture of individual parts and the installation onsite. We even make the bench seat and the key lights ourselves, as there are no usable, satisfying solutions in the market today.”
The high level of perfection shown by this organ builder is reflected in the optics, in the haptics (touch and feel) and naturally in the sound of the instruments. It also has a positive effect on their reliability. After all – quite unusual in these fast-moving times – it is typically not necessary to plan the replacement of a Laukhuff organ for more than 100 years. However, a few spare parts will still be required.
Despite the fact their high quality is globally recognized, this family-run company is still facing constant cost pressure. To achieve a high throughput in cutting applications, the company uses five CNC turning machines and three CNC milling machines – together with their latest acquisition, a five-axis CNC center (3+2) from Spinner’s U-series, with a state-of-the-industry Siemens Sinumerik 840D sl CNC onboard.
Impressive price-performance ratio
With the Sinumerik-controlled Spinner U5-620, Laukhuff uses new options for the more productive manufacturing of organ components, such as chimes
Company owner and CEO Hans-Erich Laukhuff and Production Manager Walter Rhein already had positive experiences with the CNC. However, since mid-2009, they have been relying on the Spinner machine tool factory in Sauerlach, Germany for the first time and using the U5. According to the production manager, this decision was based on the price-performance ratio and the small space required by the machine in contrast to comparable machines from other manufacturers. The U5-620 only needs 2000 x 2400 millimeters of surface area, but achieves travel distances of 620/520/460 millimeters in the X/Y/Z-axis direction.
The new Spinner machining center has high-quality individual components, including 32 tools as standard, a double arm for rapid tool changes and linear axes on roller bearing guides. Michael Schulz, Spinner sales representative at Hollenbach GmbH, confirmed, “This enables us to achieve rapid feed speeds of 48 meters per minute in all directions. Even in terms of accuracy and surface quality, our U-series sets a very high standard.”
In terms of the productivity and quality increases that can be achieved, as well, the organ builder expects the acquisition of the Spinner machine to be amortized within a relatively short period of time. Ultimately, an organ builder will often manage without time-consuming retooling, as Rhein noted, “In the cutting applications for our organ pipe tuners, we previously had to retool three times and needed around 13 minutes just for clamping – which doesn’t even take into account the downtime while retooling. The five axes mean that production is now possible in a single clamping, within about eight minutes per piece. All in all, we are at least twice as fast as a result.”
Graphically-animated user interface
Like many medium-sized contract manufacturers, this organ builder’s employees also program directly at the machine. CNC specialist Kurt Stüdlein is totally convinced about the Sinumerik 840D sl because, “…it is powerful, safe to operate, user-friendly and reliable. But the CNC user interface, tailored to shopfloor programming, also scores highly, being graphically-animated and logically-structured. ShopMill, the resident software suite, is great, particularly for beginners. Production Manager Rhein further explains, “Even a fitter who has only just finished his training, without any extensive programming experience, can work with it, after some brief instructions.”
CNC professional Stüdlein adds, “Even on complex components using the 3+2 axis machining, I can create lots of programming steps with ShopMill. If I reach the limits when entering certain contours, or if I am quicker with DIN, then I can switch from the graphic to the text-oriented DIN interface at the touch of a button.” For additional employee safety, the Safety Integrated software solution is also built into the control. This means that it is possible for the user to safely track his program’s production process in setup mode with the machine doors open.
Laukhuff is certain, based on the experience gained, that he has made the right decision with the Spinner-Siemens CNC combination. The technology and the continuously fast service from both companies have convinced him, “If there is a problem, we are helped very quickly – which is not always a given with other manufacturers in this particular industry.”

The advantages for the user are obvious. In the past, it was necessary to decide in favour of one of the three technologies. Now, with the VTC 315 DS, it is possible to choose the technology that best suits individual applications. Dr. Guido Hegener, the executive responsible for grinding technology at EMAG Salach Maschinenfabrik GmbH, comments on the diverse applications: “We are consistently following the path of combination machining. As a rule, our customers manufacture different workpieces on the machine. We intend to offer them the best technology for every application.” The VTC 315 DS is of interest to those engaged in the manufacture of medium and large batches of high-quality components such as gear shafts, rotor shafts, pump shafts, motor shafts or cardan shafts. The machining technology is chosen accordingly. Sturdy workpieces are machined using the scroll-free turning technology. The grinding technology is preferred for smaller, less stable components. “This makes us more flexible and allows us to choose the right technology for every individual requirement”, explains Dr. Guido Hegener the advantages. The machine can be used as a fully-fledged grinding machine, or a fully-fledged turning machine, or a combination of both. When choosing a technology one should take a closer look at the cycle time and, in particular, at the tooling cost. Unit production costs are usually higher with hard turning and scroll-free turning than with grinding, although CBN grinding wheels – in absolute terms – are rather expensive. It is for this very reason that the user has to decide on a case by case which manufacturing technology to use.
Different technology modules for different workpieces
The developers of the VTC were also considering the machine as an investment in the future. Should production requirements change, the machine can be equipped – at very little expense and effort – with different technology modules that make it suitable for machining of the new workpiece. At present, the technology modules available are:
This guarantees flexibility in the use of the machine and opens up a wide range of applications, especially as all the technologies can be applied also in combination.
VTC production lines
The VTC 315 DS is ideally suited for complex manufacturing processes. Whether the job includes the high metal removal rates of turning and milling or the gentler grinding process – the VTC series of machines offers the possibility to integrate most of the metal cutting processes. This allows for the creation of complete VTC production lines for soft and hard machining. Turning, milling, drilling, grinding and gear hobbing have already been modularised for this particular machine platform. It provides the VTC with an extensive field of application. “We have already installed complete production lines of VTC machines for the soft machining of crankshafts. Almost all of the operations could be accommodated on machines from the VTC series”, this is how Markus Woitsch, chief of the production team for shaft machines, explains the production line concept of the VTC. Naturally, subjects like spare part stocks and unified machine operation also play a decisive role in the eye of the customer. With a production line that interlinks a number of different VTC machines and utilises different manufacturing technologies, spare part stocks can be drastically reduced, as 80% of the VTC machine components are the same. Only the technology modules change, when a VTC has to be adapted for a new machining requirement. 
Complete-machining through technology combination
The VTC 315 DS accommodates turning as well as grinding technologies. For example, the turret carries out all turning operations, while the second station is used for the grinding work. This way, shafts can be complete-machined: the cylindrical bearing seats, the shoulders and the grooves – all machined in a single set-up. “Clamping errors play a particularly important part when it comes to high-performance components. Radial runout can be much reduced when a workpiece does not have to be re-clamped several few times”, elucidates Dr. Guido Hegener on the quality of the machine. To keep downtimes caused by tool changes to a minimum, sister tooling is provided for all turning operations. And the tool life of grinding wheels is so high that the time taken up by a wheel change is of no consequence.
The VTC 315 DS design
A distinguishing feature of the VTC 315 DS is its sturdiness and rigidity. At its heart is the machine base in Mineralit® (polymer granite). The damping properties of this material is 8 times that of grey cast iron, which makes it particularly well suited for hard machining operations like grinding or hard turning. The results are improved tool life and a better surface finish. The vertical design also aids unhindered chip flow. Manual removal of chips is hardly ever necessary. This is particularly important in soft machining, as it often involves volume-intensive chipping operations. The vertical construction is also of advantage where the footprint is concerned. Machines with horizontal spindle and tailstock take up a lot of space width-ways. That raises floor space requirements and costs money. Vertical machines develop upwards, and that – as we know – costs nothing. Automation on the VC 315 DS lies in the turret. A gripper, housed in the turret, collects the raw-part from its storage section and transfers it to the clamping position. Once the workpiece is machined, it is transferred out of the machine the same way. And thus the machine automates itself. The generously dimensioned machine assemblies, such as the work spindle with 330 Nm constant torque, and the grinding spindle with a power rating of 30 kW, have so much reserve capacity that even heavy metal removal work can be carried out on the machine. The control system used is a Siemens 840 D with EMAG grinding software that simplifies programming and operation.
The advantages of the VTC 315 DS:

Kastalon engineers match assorted textured surfaces and material hardnesses to the application.
Kastalon offers mills and processors highly engineered polyurethane mandrel sleeves, filler plates and filler rings with material hardness and surface options to match customer needs, protecting coils from damage
Kastalon brings 50 years experience in coil processing to the task of engineering a new offering of application-specific, proprietary formulated polyurethane mandrel sleeves, filler rings and filler plates. These products are designed to adapt the mandrel to handle coils with larger ID’s and addresses the problems of damage from creasing, scratching and marring at mills, service centers, toll processors and fabricators alike. Such damage is expensive for any coil handling operation, especially when the metal is prepainted or must maintain optimum cosmetic surface integrity. By the use of Kastalon mandrel sleeves, filler rings or filler plates on the uncoiler or recoiler, the inside wraps on coils are protected from metal to metal contact. More finished material is produced or usable, as a result.
Mandrel sleeves are custom designed with engineered surface hardnesses and grooved or smooth finishes, depending on the particular application. Full sleeves are usually recommended for the recoilers, while filler rings and filler plates are more often utilized for uncoilers.
The design process begins at the company website, where a detailed needs-assessment questionnaire can be completed, followed by a discussion with Kastalon engineering to formulate the proper chemistry, surface and material hardness for the application.
In use, the proprietary chemistry of the Kastalon Polyurethane material withstands the stress caused by the weight of the coil, then reforms when the mandrel is collapsed back to the rest position, owing to the inherent memory of the Kastalon engineered material. With other materials now on the market, sleeves will often sag due to memory loss and the resulting gap can cause significant coil damage. Correspondingly, additional labor and line downtime result from this condition, as realignment of the coil, sleeve and mandrel is needed. Through the true and precise sizing of the mandrel sleeve, combined with the proper material hardness and surface texturing, a Kastalon sleeve can last up to 10 times longer than rubber, fiber or even other commodity type polyurethane products, according to company research, available on request.
Mandrel sleeves, filler rings and filler plates allow coil processing to be accomplished more efficiently, whether on uncoil or recoil reels, at mills, service centers, toll processors and fabricators.
Kastalon mandrel sleeves are non-marring, cut-resistant, abrasion-resistant and offered for friction fit, requiring a separate “keeper”, or bolt-on installation. Company engineers consult customers on the amount of lubricant, cleaning solution or other coating chemistries present in the process, as this will determine the particular formulation selected. Furthermore, Kastalon offers these mandrel sleeves in a wide variety of grooved or soft surface finishes to meet the specific tension and pressure requirements of a processor’s uncoil/recoil apparatus. Special dual-durometer sleeves are also available for mills and processors where “head-in” damage is often encountered.
Kastalon engineers match assorted textured surfaces and material hardnesses to the application.
For most uncoilers, Kastalon filler rings or filler plates can provide the optimum performance for the tension, pressure and metal contact requirements typically present.
The design process for Kastalon mandrel sleeves can begin with a visit to the company’s website, www.kastalon.com, for completion of a needs assessment questionnaire. Detailed information is gathered on this form, allowing the Kastalon engineers to calculate the best sleeve design and chemical composition to suit the job.

The sales team boasts trying to commit the engineers to projects that are almost impossible while the engineers welcome the challenge and come up with ways to make them happen. Raffa explains, “With SIGMASOFT® onboard, we are able to commit to these almost impossible jobs. I know that when the customer poses new projects to us, I can go to engineering and talk about warp analysis or filling analysis and whether or not a project is even feasible. Once getting that confirmation after running the process virtually, I have the confidence to commit to a project, knowing that the information we received from the simulated run will reflect reality at least 98% of the time.” Matt Learo, Sales Manager, adds, “We had an existing customer where the materials they were using were discontinued. The customer called and requested that their new material and new tool be run through SIGMASOFT® specifically, to see how the new material was going to behave.” Stafford Frearson, Project Engineer expands, “The more complicated a project is and the more complex a configuration might be, when we are not sure how it might warp or how it might fill, there’s no question we feel more confident in going to the customer and saying, ‘this is what you are going to see’, when we have the report backing us up.” “We use other simulation software, but when the part is complex and on our harder jobs, we always run them through SIGMASOFT®,” Eric Frearson adds.
Tessy has used simulation software for over 20 years but feels adding SIGMASOFT® as one of their resources significantly changed the way they do business. Raffa told of a situation that occurred within the first few months after acquiring the new software. Most new projects Tessy acquires are first-time molded products. In most cases, Tessy helps design the part as well as the molds. Normally, all the components in the assembly are new designs. In one particular instance that Raffa described, the customer wanted to take new components and marry them to old components for a different look in the end product. Tessy learned by examining the way some of the wall thicknesses had to be designed and the way the assembly had to come together through simulation that it wasn’t optimal and the new design would simply not work. The parts that were being received from the prototype molds found warp that Tessy had never seen on these types of projects previously. The customer requested a stress and distortion analysis from an engineering company, costing them thousands of dollars, in addition to taking considerable time. Although the engineering company did provide some results and recommendations, the evidence to support these recommendations was not provided.

This became the first large project on which Tessy used SIGMASOFT®. By running multiple processes and cooling times and looking at iterations even 24-48 hours later to see how the part was going to react, it was clearly seen when pulling up snapshots and data during certain points through the process what the issue was. Tessy was able to see the part, how it cooled outside of the mold, how it flexed and how it actually got to the state where it was warped. Eric Frearson said, “It gave us evidence to show the customer that no amount of cooling changes or process changes had any effect on the problem. It was purely a design change that was needed to fix the problem. The reports provided by the software gave us the credibility and the client the reassurance to make the changes.” Raffa adds, “It essentially short cut the entire process, we didn’t try running DOEs of all different configurations or measured a ton more parts to chase something that was really not the solution.” Learo also states, “What’s reassuring about this situation was that we hadn’t used SIGMASOFT® for very long at this point and the customer was willing to pay for the stress and distortion analysis from the engineering company and see how the results compared. We found the results long before the engineering company did. When we did receive their findings, they were the same. The difference was, we were able to show why it happened and already had a solution to present our customer.” Eric Frearson adds, “Even the engineer running the analysis at the independent company was impressed. He is an experienced analyst who regularly uses a different product.”
Tessy uses virtual scientific injection molding almost exclusively, enabling their customers to save time, material and money by doing virtual studies in order to predict molding parameters. The addition of this valuable tool enables them to focus on what the final process would be. “We can now say with a very high degree of certainty what the cycle times will be and what issues we might have, before manufacturing ever sees the tool. We weren’t able to say that before having SIGMASOFT®,” Raffa said. Tessy also sees an impact of the software on manufacturing, by helping validate the process before a mold is cut. Learo adds, “We are able to give the process technicians better process parameters before we even see the mold.”

Press Conference for the Americas — EMO Hannover / Hall 25, booth D33
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 Bernd Heuchemer, Vice-President, Global Marketing and Communications, Siemens AG, Drive Technologies Division, Motion Control Systems Business, at a press conference held in the run-up to the EMO 2013 recently. “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 Heuchemer.
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 Rajas Sukthankar, General Manager, Siemens Industry, Inc., Machine Tool Systems Business. The innovations presented by Siemens at the EMO 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.
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.
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 EMO, 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.
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.
