MGEP 8 – Milling process planning – Production module optimization of toolpaths – CAPP_AI4.0 2024 (Pilot)

SUMMARY

Toolpath optimization, particularly in CNC milling, focuses on adjusting feed rates in response to areas of varying material load. By reducing feed in overloaded zones and increasing it in underloaded areas, the process becomes more efficient, reducing tool wear and breakage. Production Module helps by analyzing tool paths and recalculating forces at each rotation, interpolating new points to balance forces across the cut. This leads to smoother machining with improved tool performance. The software suggests default optimization values, potentially increasing productivity by 15-20%. Factors like allowable tool deformation, maximum chip thickness, and machine tool limitations are considered to further refine this optimization process.
