Dynamic Workpiece Handling with Sinumerik Integrate Run MyRobot
Integrated operation, programming, and diagnostics of KUKA robots via the Sinumerik Operate user interface from Siemens
Automation of machine tools will immediately become more flexible: with Sinumerik Integrate Run MyRobot, Siemens Drive Technologies Division and KUKA Roboter GmbH presented a solution for integrated operation, programming, and diagnostics of a KUKA robot in Sinumerik at EMO 2013. For example, in conjunction with the new “Run myRobot” technology, the CNC control Sinumerik 840D sl package can optimally enable KUKA robots to perform handling tasks on machine tools, in particular, loading and unloading of machining cells. Interaction, such as operation, tool retraction, teach-in, and diagnostics of robots, can be performed through just one operator panel with the Sinumerik 840D sl, thus increasing the efficiency and flexibility of the machine tools. Customer can order this technology package with immediate effect from Siemens.
As part of the dynamic automation solution, functions for handling are one hundred percent available at the Sinumerik Operate user interface. The execution of the machine tool and robot program can be tracked and controlled on screen on parallel channels. This gives the operator a quick overview of the current status of the machine tool and robot. The Sinumerik hand-held terminal HT8 and the user interface can be used to “teach” not only machine tool-related setup actions but, as part of the same operating philosophy, also the path points and functions of the robot.
Execution of the robot movements, provision of robot safety functions, and other robot-specific functions are still performed by the KUKA robot control KR C4. The Sinumerik 840D sl is connected to the KUKA control via a command interface.
With the mxAutomation function block library from KUKA, the motion sequence of the robot can be programmed completely in the Sinumerik control 840D sl. In this way, the robot program can be created completely without any knowledge of Step 7, the Siemens tool for PLC programming.

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.

Simotion Synchronized Drive Control offered for Printing and Converting Applications
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.

Precision Processing for Fast Bikes
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.

Musical and Technical Masterpieces
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
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.”
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.”

Continue readingVTC 315 DS from EMAG – The All-Rounder in Shaft Machining
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:
- soft turning
- milling (side-and-face mill)
- drilling
- gear hobbing
- hard turning
- scroll-free turning
- grinding / simultaneous grinding
- out-of-round grinding
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:
- all hard machining processes on one machine: CBN grinding, hard turning and scroll-free turning
- integrated workhandling: the EMAG tool turret reduces the costs for automation and peripherals; storage sectors for raw-parts and finished components form an integral part of the machine
- tailstock and steadies are CN-controlled; set-up and retooling times are reduced
- the hard complete-machining of shafts eliminates clamping errors
- the vertical machine construction and the resulting unhindered chip flow prevent the build-up of chip clusters
- small footprint owing to the compact, vertical construction of the machine
- short set-up and resetting times thanks to easy access and the machine’s operator friendliness
