Real-Time Collision Avoidance for Five-Axis CNC Machine Tool Based on Cyber-Physical System

Abstract

In this study, we used the game engine to develop a collision avoidance system of machine tools for low cost and quick setup applications. It can make the physical machine and the virtual reality to approximate the synchronization and realization of the cyber-physical system. Results showed that if the feed rate of the physical machine tools is 150% during processing, the executive speed of virtual machine tools can also run at 1.3 times for pre-reading NC codes. The study realizes the real-time collision avoidance for Five-Axis CNC machine tool based on the cyber-physical system.
