Siemens & KUKA Simplify Robotics for Job Shops
A new partnership between Siemens and KUKA that, using a solution developed with partner Waybo for a SYIL machine, simplifies robot integration with CNC machines. This allows smaller shops to affordably automate processes like part handling, enabling "lights-out" manufacturing -- without needing specialized robotics programming knowledge.
Siemens is pushing machine-tool automation forward with a new partnership that pairs a digital twin of its SINUMERIK 828 CNC with a KUKA robot. The integrated system streamlines part-handling tasks and simplifies both operation and programming, giving small and mid-sized shops a practical, high-impact automation upgrade.
Bringing the concept to life during a recent tradeshow, KUKA Robotics demonstrated the same control and its robot working in tandem with a SYIL vertical milling machine. The machine featured the SYIL R1 machine-tending automation package, developed with one of KUKA's System Partners, Waybo, which seamlessly integrates the pick-and-place, part articulation, and communications with the CNC onboard, all at a very attractive price point.

The goal of the program, according to Frans Buikema, chief marketing officer at SYIL, is to offer the small and mid-sized shops an entry point into automation without major capital investment. Likewise, as Ron Bergamin, key technology manager for Machine Tool Automation at KUKA, adds, the ROI can be very short, as this automation advancement allows the addition of a lights-out second or third shift at job shops of almost any size. Automation is the key, and this cooperative engineering venture has opened a new chapter for small to mid-sized machine shops.
Simplifying robotics through the CNC
A bit of history. Only a decade ago, the integration of a robot with a machine tool required a separate learning curve for the shop, as robotics required special programming and teach-in communications, a separate pendant for operation, and other challenges that often required outside consultants to implement. For small and mid-sized machine shops, this barrier, combined with the cost involved, resulted in today's market condition, where less than a quarter of the smaller job shops in America utilize automation -- and especially robotics -- in their workday.
History has advanced. As Tiansu Jing, product manager, SINUMERIK CNC systems, explains, "The benefits of this development for the busy job shop are many. Setup, programming, operator interface, and diagnostics are all improved with the SINUMERIK Run MyRobot/Handling application, as it easily incorporates the KUKA robot with the SYIL machine tool." The teach-in functions are implemented through the SINUMERIK Operate HMI system on the control, while the proprietary SINUMERIK Run MyRobot/Handling capability of the CNC seamlessly integrates with the KUKA robot control.
Jing further notes that, since there is no need to learn robotic programming, start-up time is reduced and the robot's separate control pendant is eliminated, simplifying the operator's task. The SINUMERIK control's HMI is used to operate both the machine tool and the robot tender, with all commands and operating conditions displayed on a single screen. Jing says the greatest value for the busy job shop comprised the system's ability to integrate robots on all its machines, while economizing the learning curve for all the operators. This entire cooperative venture between Siemens, KUKA, and SYIL has made this advancement possible.
The robot arm is integrated into the CNC, so programming, operation, and diagnostics are all accomplished for the machine tool and robot on the single control screen of the HMI.
From complexity to clarity
The SINUMERIK 828D CNC utilized in this application is designed for the job shop market's use of turning centers, milling machines, and vertical machining centers (VMCs), but it also offers machine builders and end-users the flexibility to enhance the productivity of those machines with this new robotic automation, integrated directly into the control. As Jing points out, "The 828 is scaled to the functionality of the standard machines sold to the smaller job shops. With Run MyRobot/Handling included, programmers can use the same G-code for the robot and the machine tool."
Designed for the job shop, including affordable lights-out manufacturing
As KUKA's Bergamin notes, "Machine builders can now offer robotics from KUKA PLC mxAutomation, a universal PLCopen-certified PLC interface. It allows the user to program and operate all important robot functions directly in a busy shop's familiar control environment."
Jing adds that the Run MyRobot/Handling application allows the machine builder to offer robotics as another option, at a far more affordable price than in the past, as all the engineering effort has been substantially reduced. With the connection of Ethernet and safety cables to the robot, the SYIL customer finds it's much easier to connect the robot. Bergamin says that the robot can be up and running in a day, in most cases. "With the addition of a lights-out second or third shift at the shop, the spindles keep turning and the shop makes more money. Plus, the ROI is very fast with this setup," he adds.
Jing concludes, "The machine builder can easily add their own robot-specific screens to display the robot tasks and improve the usability. This solves long-time challenges for both the machine builder and end-user alike. Machine tool builders like SYIL can now offer robotic packages to their customers with less price pain and more advantages in the shop."
Philip Peloso, business development manager for Machine Tool Automation at KUKA, adds, "We saw a resident robotic talent gap as well as price resistance in the smaller machine shop sector and decided we needed to pursue a solution. We turned to our Official System Partner, Waybo, presenting them with the facts. This solution would be an entry-level venture, addressing the 75% of the job shops who currently have no robotic automation on their floors. We sought to present them an easy-to-use, robust system that allowed quick changeover for the busy shop doing multiple jobs or families of parts during the day."

Because KUKA has a long-time relationship with Siemens, their combined support in the field brings a further benefit to the solution. Once developed, this new system was presented to SYIL, who adopted it as their SYIL R1 solution for the job-shop market. Peloso says the key value proposition is that, "All meaningful controls and diagnostics were to be displayed on the CNC, thereby reducing or eliminating all the previous roadblocks for the shop personnel." All the motion control of the grippers, pick-and-place functionality, and communications with the CNC on workholding are seamlessly transmitted from an application layer on the KUKA robot, so all commands are configured and programmed to take instructions directly from the CNC.
Bergamin says, "Working with Waybo, we developed the automation around the robot. A new interface layer, run through our standard mxAutomation software, allowed the robot control from the Siemens CNC, so a single pendant is all that's required to run the SYIL machine tool and the robot package. All diagnostics are under the hood."
A new benchmark for machine tool builders
On the tactical business level, Siemens had been providing CNC technology to SYIL globally and brought the concept of robotic integration to KUKA, who worked closely with their partner Waybo to design and implement the package that became SYIL R1 automation.
Buikema of SYIL details this development from the machine builder perspective. "We've long had automation in our company's vision and road map for the future," he says. "As we focus on the small and mid-sized machine shop world, we constantly encounter the lack of skilled labor, the price resistance, and the shortage of robotic knowledge in this sector of the machine tool market."
Next-level automation: Full integration of robotics into the machine tool, realized today through the partnership of Siemens, SYIL, and KUKA.
Wesley Wang, managing director for SYIL in North America, adds, "We have recently partnered with Titans of CNC to market our machines here, and we feature the SINUMERIK 828D CNC on most of our equipment, as it offers great motion control, monitoring, and communications capability, plus the onboard capacity to engage machine-tending robotics, which opens the 24/7 running option to our customers in ways they have not imagined in the past.
Real results on the shop floor
Buikema cites some hard numbers. "We believe we can tell our customers that automation is accessible today in new and exciting ways. It is decidedly not too complicated nor is it a major capital investment. For a $60,000 package, they can be looking at a payback period of a year or less."
Wang adds, "It's all about knowing your options today and how different they are from the not-too-distant past in the machine tool world."
Expanding the vision
SYIL currently designs and builds CNC milling machines, CNC turning centers, and CNC Swiss-type lathes. According to Buikema, "This development with Siemens and KUKA represents our own entry into robotics, and we plan to expand the use of such packages onto all our machine offerings very soon." He calls the implementation of the SINUMERIK 828D CNC with Run MyRobot/Handling "... a real game changer, because it enables us to start creating more automation packages and make them accessible to our audience, the small to mid-sized machine shops." The SYIL R1 automation package utilizes the same technology integration shown by Siemens and KUKA at recent industry tradeshows.
Commenting on the relationship between SYIL and Siemens, Buikema says, "It grew from supplier to strategic partner very quickly. The engineering support at Siemens collaborates with our own machine tool engineers at SYIL on virtually all new machine developments at our company. This enables us to expand our machine range much faster and better than we could do on our own. That's true synergy."
Of equal importance, Buikema cites the support his company gets from Siemens in the North American market. "The help they provide to our dealers in Canada, the United States, and Mexico is invaluable. It allows our dealers not only the ability to sell a higher level of machine and automation, but also the software support to fulfill the needs of all our end-users."
The SYIL R1 automation package includes a standard pneumatic clamping force block
and an optional dual gripper, used when the finished part is a different shape from the blank.
The SYIL R1 machine-tending system, incorporating the KUKA robotic technology, is currently offered as a standard package by the machine builder, for parts up to 3 kg (6.61 lb), a payload of 6.7 kg (14.77 lb), and a reach of 901 mm (35.47 in). It offers an IP65/67 rating for harsh operating environments. It facilitates the loading and unloading of metal parts from the cutting zone and workholding devices being utilized, plus it is quick to install and easy to operate from the SINUMERIK 828D control.
The R1 system from SYIL removes the manual and repetitive tasks for a CNC machine operator by automating the load/unload process. It is an ideal solution for high-mix, low-volume tasks and can be fully integrated with parts conveying systems, bins, and pallets. The R1 system is offered with a standard workholding package, featuring pneumatic clamping force block design, as well as a dual-gripper option when the finished part has a differing final shape from the blank.
In addition, the SYIL R1 system features an "everything on one screen" format, integrating the robot's programming and operation in the SINUMERIK 828D control, using NC G-code and robot teach-in function for programming. This makes it very easy for machine tool operators to learn and use. All the robot diagnostic data is shown on the same HMI as the machine, allowing the entire automation cell to be monitored without the need for a second pendant.
Robot and part programs are both resident in the CNC and accessed through the SINUMERIK Operate
graphical user interface. Robotic functions such as programming, manual travel, teach-in, and diagnostics
are directly executed from the CNC through the SINUMERIK Run MyRobot/Handling application.
According to Buikema, the SYIL R1 automation package can be installed and fully operational in less than one day. The system is expandable with custom solutions and various pallet drawers provided.
The future of shop-floor automation
Increasingly, more job shops and machine operators are seeing that automation is an important asset when striving to achieve consistent workpiece quality and more flexibility on the shop floor. Digitalization facilitates the higher level of automation needed and the networking of the components involved. With this new development, Siemens is offering a cost-effective solution that incorporates the KUKA robot functionality with a line of affordable machine tools, in this case, the SYIL brand of machining centers and lathes for small to medium job shops.
All functions of the machine and the robot can be monitored on a single pendant, eliminating the need
for a second robot pendant.
From the KUKA perspective, Bergamin says, "KUKA offers machine tool builders and end-users alike the ability to incorporate advanced robotics into their equipment and onto their shop floors, with the goal of optimizing productivity and reducing operator workload. Our partnership with Siemens has resulted in the synergy that brought this development to life. It substantially expands the ability of the small and mid-sized shops to utilize robotics in their work environment."
