Research on Postprocessor of DMU50 CNC Milling Machine Tool Based on Edgecam
For the CNC milling in DMU50 machine tool, the problem to constructing postprocessor based on Edgecam software is researched. In this paper, The general flowchart of post-processing was concerned, the technology of kinematics and the method of construction were proposed, then, the postprocessor of SIEMENS 840D was created by Edgecam, at last, the correctness and validity of the method was certified by simulation and machining in experiments. INTRODUCTION Edgecam is intelligent CNC programming software for CNC lathing, CNC milling, CNC wire cutting, turn-milling machining developed by VERO Company, which widely used by many customers. Post-processing can translate the CAM programming operations to the specific CNC machine instructions, the quality of which determines the quality and efficiency of programming[1,2]. Post-processing in Edgecam integrates with CAM programming operations to easily generate NC programs for mainstream machine tools and CNC systems, construct kinematics models and geometry models of machine tools, which can simulate part machining in CAM programming and check collision. _____________ Tiegang Li, Mechanical School, Shenyang Institute of Engineering, 18 Pu Chang Street, Shenyang, Liaoning Province 110136, P.R.C.
