Software, Stäubli, and Beckhoff technologies form a new CNC solution

In a significant advancement for the industrial automation sector, machine-tool provider CNC Solutions has unveiled a groundbreaking new CNC solution, developed in collaboration with Stäubli, Beckhoff Automation, and ENCY Robot software. This integrated "Technology Package" is designed to overcome the long-standing limitations of traditional robot teach-in methods, particularly for complex, high-precision manufacturing tasks such as multi-axis milling, abrasive sanding, and laser or plasma cutting. The solution marks a pivotal shift towards enabling industrial robots to perform with the accuracy, repeatability, and streamlined workflow characteristic of dedicated CNC machine tools.

The Evolving Landscape of Industrial Automation and the Challenge of Complexity

For decades, industrial robots have been instrumental in automating repetitive tasks, primarily excelling in simple pick-and-place operations. Their adoption has been driven by the promise of increased efficiency, safety, and productivity. However, as manufacturing processes have become increasingly sophisticated, demanding higher precision, greater flexibility, and the handling of millions of motion points, the inherent limitations of conventional robot programming methods have become glaringly apparent. Traditional teach-in methods, which involve manually guiding a robot through a sequence of points, are time-consuming, prone to human error, and fundamentally inadequate for the intricate path planning required by CNC-class workloads.

Modern manufacturing operations, from intricate component milling in aerospace to high-speed trimming in automotive and abrasive sanding in various industries, necessitate a level of path control and repeatability that far exceeds what manual teaching can provide. The sheer volume of data points, the need for continuous toolpath adjustments, and the requirement for seamless integration with design data from Computer-Aided Manufacturing (CAM) software have created a significant gap. Without a robust, integrated solution, manufacturers face substantial challenges, including prolonged commissioning times, inconsistent product quality, and underutilized robotic assets. This scenario often leads to idle robots, extended project timelines, and increased operational costs, hindering the full realization of automation’s benefits.

CNC Solutions’ Journey Towards a Unified Robotic CNC Platform

CNC Solutions, a company with a rich history spanning several decades in supporting complex manufacturing projects, recognized this growing disparity. Their experience with increasingly demanding applications – including advanced multi-axis machining, precision grinding, and high-speed cutting – highlighted the inadequacy of traditional controller-centric robotic methods. The company embarked on a mission to develop a workflow that could seamlessly bridge the gap between CAM design and robot execution, ensuring CNC-level precision and speed.

The development of the "Technology Package" was not an overnight endeavor but an iterative process of refinement. The engineering teams at CNC Solutions dedicated considerable effort to fine-tuning robot axis motions, striving to achieve the consistency and reliability typically associated with dedicated CNC machines. This meticulous approach was crucial in developing a standardized, repeatable solution that integrators could readily implement across diverse manufacturing environments. The goal was to empower robots to function not merely as automated manipulators but as true machine tools, freeing operators to concentrate on production optimization rather than manual robot intervention.

The Core Pillars of the Integrated Technology Package

The innovative solution is built upon three foundational components, each contributing critical functionality to create a cohesive and powerful robotic CNC system:

1. ENCY Robot: The Advanced Offline Programming and Simulation Hub
   At the heart of the solution’s intelligence is ENCY Robot, a sophisticated offline programming software developed by ENCY. This platform serves as the central brain, calculating intricate toolpaths and conducting comprehensive simulations of the entire robotic cell. Its primary advantage lies in its ability to eliminate the need for time-consuming online programming, a process that traditionally keeps the robot idle for extended periods. Instead, ENCY allows for complete virtual prototyping and validation.

   ENCY’s capabilities extend beyond basic path generation. It performs crucial checks such as axis limit validation, singularity avoidance, and full collision detection, significantly de-risking the commissioning process. This transforms what would typically be unproductive downtime into valuable preparation time. The platform provides an all-in-one environment for design, technology setup, toolpath calculation, and simulation, boasting a zero-code digital-twin builder and extensive libraries. This robust functionality ensures that trusted CAM strategies are directly and reliably translated into executable robot instructions, minimizing potential errors and maximizing operational efficiency.

   ENCY was specifically chosen for its broad functional spectrum, capable of handling everything from relatively simple two-axis tasks to highly complex multi-axis cells. Its internal management of code paths and models guarantees transparent system behavior, which is vital for high-precision applications. This offline programming paradigm drastically reduces the time to the "first good part" by allowing complex path planning and optimization to occur virtually, thereby minimizing on-site adjustments and rework.

2. Beckhoff Automation: The Precision Motion Control Engine
   Providing the critical control layer for the Stäubli robot is a Beckhoff motion controller. This advanced controller operates the robot using standard CNC commands, mirroring the familiar language and functionality of traditional CNC machine tools. This includes precise control over feeds, modes (such as Auto, Manual, and Home), and frames, ensuring a seamless and intuitive interface for operators already familiar with CNC systems.

   The Beckhoff controller integrates seamlessly with the overall system, allowing for the execution of complex trajectories generated by ENCY with CNC-level accuracy and speed. Its robust architecture supports critical features like feed overrides, ensuring operational flexibility, and integrates emergency-stop logic for enhanced safety. The system also provides essential process I/O and communication interfaces for plant networks, supporting speed control during automatic operation and enabling manual moves via encoder-wheel controls. This integration of a powerful, industry-standard motion controller is pivotal in transforming a standard industrial robot into a highly capable CNC machine.

3. Stäubli Robotics: The Robust and Accurate Execution Platform
   The physical execution of these precise commands is entrusted to Stäubli robots. Stäubli is renowned for engineering robots that offer exceptional precision, superior repeatability, and a robust, sealed construction. This last feature is particularly critical for abrasive applications like grinding and milling, where dust and debris are prevalent, ensuring long-term reliability and minimal maintenance.

   The Stäubli robots are integrated with a CNC-style motion layer for trajectory execution, providing the necessary mechanical fidelity to translate complex digital instructions into precise physical movements. This combination of inherent robot quality and specialized motion control is indispensable for applications demanding high accuracy and consistent performance in challenging industrial environments. The plug-and-play wiring, connecting the Stäubli robot to the Beckhoff controller with a single cable, exemplifies the system’s focus on ease of integration and rapid deployment.

Addressing Real-World Manufacturing Complexities and Operational Advantages

The "Technology Package" is engineered to tackle the practical challenges encountered in real-world manufacturing cells, which often deviate from idealized specifications. It includes advanced features that typically require significant setup time in conventional systems, such as:

• Absolute, TCP, and Frame Calibration: Essential for ensuring the robot’s physical movements precisely match its digital model, especially critical after tool changes or reconfigurations.
• Singularity Management: Proactively identifies and avoids robot postures that could lead to unpredictable behavior or damage.
• OPC UA Connectivity: Provides a standardized communication interface for seamless integration into broader plant networks and Industry 4.0 ecosystems.
• Real-time Path Adjustments: Allows for dynamic modifications to toolpaths based on sensor feedback or process variations, enhancing adaptability.
• Tool-Wear Compensation: Automatically accounts for tool degradation, maintaining consistent part quality over extended production runs.

These features, delivered within the package, dramatically reduce the commissioning effort and enhance the system’s adaptability. The predefined and machine-tuned processes, including milling, welding, sanding, laser cutting, grinding, deburring, polishing, blasting (wet/dry), waterjet cutting, cladding, painting, cleaning, and gluing, provide integrators with a validated starting point, significantly accelerating deployment.

A key metric for industrial integrators is the speed at which they can transition from robot installation to producing the first quality part. By eliminating the need for online robot teaching and providing a sophisticated CNC-like motion layer, the ENCY-driven system allows teams to reallocate their focus from manual programming to critical aspects like fixture design, tool selection, and process optimization. This strategic shift leads to tangible benefits:
