Abstract
En 中文
• Predictive shadow model enables pre-contact collision detection in CNC machining. • Sensor-free online simulation provides active safety for CNC operation. • Hierarchical replanning reduces path generation latency by over 95%. • Autonomous retraction replaces passive emergency stops in CNC machining. • A 136 ms safety response is validated on a real three-axis CNC testbed.
