| Outline of Final Research Achievements |
In order to implement process monitoring in major machine tools with ball-screw driven mechanism, a novel cutting force estimation technology with state-fused disturbance observer based on multi-inertia model was proposed. It is experimentally clear that highly accurate process monitoring has been conducted by integrating all cutting forces estimated from each axis. In this study, tool wear and fracture detection techniques, and chatter detection technique are developed with estimated cutting force.
