Abstract
Summary The study deals with the general method of generating NC data from collision-free tool path of 5-axis control machining centers. The use of 5-a.xis control machining centers, capable of machining complicated workpiece shapes efficiently and accurately, is recently increase. Then it is inevitable to generate collision-free CL data and NC data rapidly. CL data He generated by the main-processor having the collision avoidance procedure between a workpiece and an arbitrary tool shape. based on the solid modeling technique. The postprocessor developed in the study can convert CL data to actual NC data. taking account of the structure of machining centers. The main- and post-processors are experimentally found effective.
