AI Technical Summary

Technical Problem

Existing technologies in five-axis linkage CNC machining lack coordinated optimization of tool posture adjustment and path continuity, resulting in frequent surface defects and insufficient stability of the machining process. It is difficult to balance machining efficiency and quality, especially when machining complex curved parts, which is prone to vibration and obvious tool marks.

Method used

By extracting key control points, performing iterative optimization and finite element analysis, a smooth machining path is generated. The machining parameters are then optimized in conjunction with the CNC instruction sequence to achieve coordinated optimization of tool posture and path.

Benefits of technology

It significantly improves the stability and quality of the five-axis linkage machining process, reduces the risk of surface defects in parts, and achieves a synergistic improvement in machining quality and efficiency.
