1Productivity
If correction parameters are optimized for overall machining shape, then general machining performance improves, but specific problematic parts do not receive targeted optimization
Solution Approach 1:
The system segments the machining process into part-specific evaluations, where each part is assessed independently for machining accuracy. This segmentation allows the learning unit to identify which specific parts require correction parameter optimization, enabling targeted improvements without compromising overall machining efficiency.
Solution Approach 2:
The patent implements feedback mechanisms where the state observation unit continuously monitors machining results for each part, and the learning unit uses this feedback to iteratively optimize correction parameters. The determination results from each part feed back into the learning process, allowing the system to adapt and improve correction parameters based on actual machining performance of specific parts.
