This paper describes a method of collision avoidance on the tool path generation for 5-axis control machining. The proposed method is able to avoid the collision between tool and workpieces. In the method, the avoidance angle and avoidance direction without collision are analytically calculated under the continuity for the tool-posture and machining conditions. A prototype CAM system has been developed in this study. This system is composed of the tool path generation module, post-processor and NC-simulation, in order to deal with the collision at the cutting points which are generated by linearization process. And it has been applied to machining for a marine propeller. As a result, the validity of the proposed method is experimentally confirmed.
