Introduction to CNC Digital Twin Technology
Mitsubishi Electric Corporation, in collaboration with RWTH Aachen University in Germany, has made a significant breakthrough in the development of digital twin technology for computer numerical control (CNC) machine tools. This innovative technology uses a digital twin to correct machine-tool errors in real-time, resulting in improved productivity and reduced environmental impact.
How the Technology Works
The digital twin technology uses a proprietary compact physical model, composed of a minimum number of equations, to estimate machining errors. This model is created using large amounts of data, including axis positions, currents, and cutting forces, acquired at a high sampling rate of up to 1 kHz. The technology extracts only the necessary information for estimating machining errors and feeds the results back into the control system in real-time.
Comparison of Digital Twin Technologies
| Technology | Sampling Rate | Error Reduction | Environmental Impact |
|---|---|---|---|
| Mitsubishi Electric's Digital Twin | Up to 1 kHz | Up to 50% | Reduced waste and energy consumption |
