Abstract

Five-axis complex surface machining on a Computer Numerically Controlled (CNC) machine needs CAD/CAM system for the cutter location and orientation data. Since these data are defined with respect to the coordinate system of work-piece, they need to be converted to the machine’s control commands in machine coordinate system, through processing so called a CNC post-processing. In this work, a kinematic model method and a efficient algorithm for CNC post-processing have been presented for a typical five-axis milling machine of table rotating/tilting type. The proposed algorithms have been realized in our developing CNC system.
