离散曲面慢刀伺服车削刀具路径规划
Cutting Path Plan of Discrete Surface for Slow Tool Servo Turning
摘要
Abstract
To solve the difficulties of discrete surface processing,the cutting path plan for discrete surface was discussed.The generating algorithms of cutting contact points and cutting location points were proposed.The two kinds of velocity interpolation algorithms for cutting location points were compared.A cutting contact points generation method based on the Zernike polynomials using local points data fitting and a Z-direction cutting tools geometry compensation method were proposed.In order to verify the accuracy of the cutting path plan,the MATLAB software was used in simulation of toric spectacle lenses.The cutting path plan and processing experiments for both toric spectacle lenses and progressive-addition lenses proved that discrete surface can be successfully and accurately machined by the proposed method without whole surface points data fitting.关键词
