Study on Post-processor for 5-Axis Control Machining Centers

Abstract

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-axis control machining centers, capable of machining complicated workpiece shapes efficiently and accurately, is recently increased. Then, it is inevitable to generate collision-free CL data and NC data rapidly. CL data are 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 post-processor developed in the study can convert CL data to actual NC data, taking account of the structure of machining centers, linearization, feed rate control and spindle rotation control. The main-and postprocessors are experimentally found effective. © 1992, The Japan Society for Precision Engineering. All rights reserved.
