In a significant advancement for industrial automation, machine-tool provider CNC Solutions has unveiled a groundbreaking "Technology Package" that seamlessly integrates advanced software, robust robotics from Stäubli, and sophisticated motion control from Beckhoff. This innovative solution addresses the growing demand for high-precision, robot-driven manufacturing processes that transcend the limitations of traditional teach-in methods, particularly for complex CNC-class workloads such as multi-axis milling, abrasive sanding, and laser or plasma cutting. The collaboration marks a pivotal step towards blurring the lines between the flexibility of industrial robots and the uncompromising precision of Computer Numerical Control (CNC) machines.
The Evolving Landscape of Industrial Automation and the Need for a New Paradigm
For decades, industrial automation has seen a distinct division: traditional CNC machines excelled at intricate, high-precision tasks requiring continuous path control, while industrial robots offered unparalleled flexibility, primarily for repetitive pick-and-place operations. However, the modern manufacturing landscape, driven by demands for mass customization, complex geometries, and higher material removal rates across various industries—from aerospace and automotive to medical and mold & die—has rendered this traditional separation increasingly inadequate.
CNC Solutions, with its deep-rooted experience spanning decades in supporting increasingly complex projects, recognized that the established "teach-in" approach, while effective for simpler tasks, fundamentally struggled with the sheer complexity of today’s advanced manufacturing. Processes like precision milling, intricate trimming, and advanced sanding necessitate the management of millions of motion points. Manually teaching a robot such a trajectory is not only prohibitively time-consuming but also prone to inconsistencies, making it unsuitable for applications demanding micron-level accuracy and repeatable quality. This often resulted in significant robot idle time, extended project timelines, and variable product quality, hindering the adoption of robots in high-value, high-precision applications. The challenge was clear: how to imbue industrial robots with the precision, control, and programming ease of a CNC machine.
CNC Solutions’ Vision: Bridging the Gap with the "Technology Package"
Driven by the imperative to overcome these limitations, CNC Solutions embarked on developing a workflow that would fundamentally redefine robot programming and execution for complex tasks. Their vision culminated in the "Technology Package," a comprehensive solution designed from the ground up to integrate Computer-Aided Manufacturing (CAM) at its core, allowing for precise offline simulation of the entire manufacturing cell, and ultimately, controlling a robot with true CNC-level precision and speed.
"Our goal was to eliminate the compromises traditionally associated with using robots for high-precision machining," stated a representative from CNC Solutions, emphasizing the transformative potential of the package. "We wanted to empower integrators and manufacturers to leverage the inherent flexibility of robots without sacrificing the accuracy and repeatability expected from a CNC machine. This required a holistic approach, meticulously integrating software intelligence with robust hardware."
The development process for this integrated stack was iterative and rigorous. Over time, the CNC Solutions team painstakingly refined the robot axis motions, gradually perfecting the commissioning process until it achieved the unwavering consistency characteristic of a dedicated CNC machine. This methodical approach ensured that the final solution was not merely a collection of components but a truly standardized, integrated system capable of reliable, high-performance operation.
The Three Pillars of Precision: Software, Robotics, and Motion Control
At its heart, the "Technology Package" is built upon three core, synergistic components that work in unison to deliver unprecedented capabilities:
-

ENCY’s capabilities extend far beyond simple path generation. It performs meticulous simulation of the entire manufacturing cell, offering critical features such as real-time collision detection, singularity avoidance, and checks against axis limits. This proactive approach converts what would typically be commissioning time into productive time, ensuring that programs are validated and optimized before ever reaching the shop floor. Its "zero-code digital-twin builder" and extensive libraries streamline the programming process, making complex tasks more accessible. Crucially, ENCY translates trusted CAM strategies directly into reliable robot instructions, ensuring that the precision envisioned in the design phase is accurately executed by the robot. The software’s broad functionality, capable of managing both simple two-axis tasks and highly complex multi-axis cells, along with its transparent internal management of code paths and models, made it the ideal choice for CNC Solutions. This allows teams to focus on process optimization rather than grappling with vendor-specific robot languages. -
Beckhoff Motion Controller: The CNC-Style Command Center:
Serving as the central nervous system, a Beckhoff motion controller is integral to the package. Beckhoff Automation is renowned for its open, PC-based control architecture, particularly its TwinCAT software platform, which integrates PLC, motion control, robotics, HMI, and communication functionalities into a single environment. In this solution, the Beckhoff controller operates the Stäubli robot with standard CNC commands, effectively transforming the robot into a multi-axis CNC machine. This means operators can utilize familiar CNC paradigms, including feeds, modes, and frames (akin to G-code and M-code), simplifying the transition for those accustomed to traditional machine tools.
The Beckhoff controller’s high-speed processing capabilities and deterministic real-time performance are critical for executing the complex, continuous paths generated by ENCY with the necessary precision and smoothness. Its open architecture also allows for seamless integration with other plant networks and communication interfaces (like OPC UA), fitting perfectly into modern Industry 4.0 environments. -
Stäubli Robot: The Precision Executioner:
The final, indispensable component is the Stäubli robot, responsible for the physical execution of the meticulously planned trajectories. Stäubli robots are highly regarded in the industry for their exceptional precision, repeatability, and robust construction. These characteristics are paramount for the abrasive and high-demand applications targeted by the "Technology Package," such as grinding, deburring, polishing, and precision milling. The robots’ sealed construction effectively resists dust and debris, a crucial feature in harsh manufacturing environments where contaminants can degrade performance and shorten lifespan.
Moreover, Stäubli provides seamless integration of a CNC-style motion layer for trajectory execution, working in perfect harmony with the Beckhoff controller. This synergy ensures that the robot can accurately follow the complex paths generated by ENCY, maintaining tight tolerances and consistent surface finishes. A representative from Stäubli might observe, "Our robots are engineered for demanding industrial environments, and this collaboration showcases their capability to deliver CNC-level performance, pushing the boundaries of what’s achievable with robotic automation."
