摘　　要：为解决带旋转刀具中心点(RTCP)功能五轴机床的后处理问题,以国产桌面式双回转工作台型五轴机床结构为研究对象,对其运动链进行了分析和建模,建立了其正向运动学方程;对旋转轴和平动轴分别进行了反向运动学求解,分析了旋转轴双解问题的求解策略;同时结合五轴机床的RTCP功能,开发了一套通用性较强的后置处理程序。最后对后处理程序进行了五轴加工实验,验证了该程序在实际应用中的正确性和有效性。In order to solve the post-processing problem of the five-axis machine tool with RTCP function,the domestic desktop double-rotary table five-axis machine tool is used as the research object.The inverse kinematics solution of the axis of rotation and the translation axis is obtained,and the solving strategy of the double solution problem of the axis of rotation is analyzed.The post-processing procedure considering the RTCP function with strong versatility is developed.Finally,the actual five-axis machining experiment is carried out,and the results verify the correctness and effectiveness of the program in practical application.
