Conventional collision prevention systems for machine tools such as collision prevention functions on NC controllers are based on simulations using 3D models of work pieces that are made in advance. If the setting up of work pieces differs from the models, then collision accidents are unavoidable. Therefore, a collision prevention system for detecting work-piece setting defects of machine tools by simulation based on actual conditions from NC controllers and measurement data of work-pieces using 3D laser scanning is proposed. A collision prevention system for 3 Axis machine tools based on this concept had been developed in success. Moreover, a collision prevention system for 5 Axis machine tools has been developed. This paper presents a system concept, overview of the collision prevention system for 5 Axis machine tools.
