基于边等距偏移的环切加工刀具路径生成方法
Contour-parallel Tool Path Generation Method Based on Pair-wise Offset
摘要
Abstract
A contour-parallel tool path generation method was proposed based on pair-wise offset to solve the problems of generating contour-parallel tool paths,which were composed of lines and arcs.The convex vertex and interfering concave vertex of closed contour were used as a start point re-spectively,and the local and global invalid areas of contour including lines and arcs were identified re-spectively with the method combining pair-wise-interference-detection(PWID)procedures and arc seg-mentation processing.Non-interference contour-parallel tool path was generated by offsetting the closed contour without invalid area.The proposed method was realized in the self-developed CAD/CAM software.The simulation results show that the tool path without interference area may be gen-erated accurately and effectively with the proposed method,and may be applied to closed contours with islands as well.关键词
