Determination of Collision-free Tool Orientation for RTCP
摘要
Abstract
Aiming at reducing the nonlinear errors and preventing angular velocity overrun,a RTCP algorithm based on angle interpolation was proposed herein.The problems of global interference during interpolation were analyzed,and then an interpolation error factor formula was derived.Finally,a collision-free region of RTCP algorithm was obtained.The algorithm can reduce the nonlinear errors effectively,ensure the rotation axes movement smoothly,improve the machining efficiency by ensuring that CNC codes need not to be generated by postprocessing software when tool length changes.Simulation results demonstrate the effectiveness of proposed algorithm.关键词
