The Research and Development on The Post-processing Algorithm for Four-axis CNC Machines With Swing-head and Tilt Platform

摘要

To make up the deficiency problem of post processing of CAM software in four-axis machining, a postprocessing algorithm is studied which based on the four-axis CNC machines with swing-head and tilt platform. Firstly, the algorithm reads the position coordinates and unit normal vectors of every cutter location point on curved surface from the cutter location files; secondly, the actual shift of machine is gotten by coordinate transition and swing, and then generating the CNC codes according to the definition of the machine; at last, practical machining validates that the algorithm is correct and applied.
