A Study on Tool interference avoidance in machining adie cavity

When machining a die cavity, many machining conditions must be considered. Especially when using a NC machine, The tool interference is a improtant problem. In this paper, we consider the tool interference of free-formed surfaces and analytic compound surfaces which having free_formed base and many primitives and present a method checking the tool interference regions and avoiding them
