基于有向图的刀轴矢量优化研究
Research on Tool Axis Vector Optimization Based on Graph
摘要
Abstract
According to the five axis NC machining of ball end milling,this paper presented a new method to optimize tool axis vector based on graph.Based on the characteristics of the cutter axis vec-tor data,the minimum optimization model and algorithm of the cutter axis vector directed graph were proposed.This method can get global minimum cutter axis vector variation of cutter axis vector se-quence and improve the computational efficiency of the algorithm by using the boundary of the feasible region of cutter axis vector j oining in the directed graph calculation.Simulation and data analyses show that the proposed method improves the continuity and smoothness of cutter axis vector in a certain ex-tent,and also has certain applicability in its optimal tool posture along the boundary of the feasible re-gion.关键词
