Recently in die and mold machining, there are demands for further reduction of lead time and cost to increase global competitiveness, and 5-axis machining is drawing its attention as a solution. With 5-axis machining, tilting of tool allows highly rigid thick tooling to be used over wide area, which enables reduction both machining time and number of tool used. But unlike conventional 3-axis machining, complex thinking process such as selecting the posture of tool taking in account of collision is needed, which distresses the operator and also consumes great portion of time compared to actual machining time. Here, to shorten the total lead time starting from process planning to machining, support system which automates process planning, which allows even novice to plan high efficiency indexed 5-axis process in short time, has been developed.
