In case of the five-axis controlled machining, there is interference problem among tool, workpiece, jig, machine structures such as table and spindle. In this study, these 3D models were loaded to CAM, and, moved to position corresponding to candidates of all tool postures on tool path. Then, by performing interference judgment, candidates of tool postures without interference were calculated. Therefore, tool path without interference was generated. When interference judgment is performed, process time was shortened by parallel processing using GPU and polygon model. Additionally, this CAM was corresponded to all types of five-axis controlled machining, table-tilting type, table/spindle-tilting type, and spindle-tilting type, and, improvement of general versatility was conspired. Finally, as the result of the machining simulation using all types machining, the effectiveness of the devised technique was confirmed.
