AI Technical Summary
Existing technologies cannot achieve tooth-by-tooth monitoring of wear on micro-milling cutters, especially when the wear of multiple cutters is unevenly distributed, making it impossible to monitor each tooth individually using cutting force signals.
By acquiring machining information and cutting force signals, the chip load model is reconstructed, the equivalent radius difference of each cutting tooth is extracted, the instantaneous chip load thickness is calculated, and the flank friction coefficient is extracted based on the cutting force signal. Finally, the flank wear width of each cutting tooth is calculated.
It enables tooth-by-tooth monitoring of wear on micro-milling cutters, providing comprehensive and reliable tool wear information, improving the accuracy of micro-milling, preventing tool breakage and machine tool damage, increasing processing efficiency, and reducing production costs.
