Equal base cone gear is a new kind of curve gear based on numerical control technology. Now its manufacturing method have no experienced dada which can be referenced. The cost of traditional manufacturing method is higher and its efficiency is lower. This paper applies PC simulation technology to NC machining, and it presents cutting tool path mathematic model. Through practical processing have been accomplished in the laboratory, the practical result is in accordance with the result of computer simulation. It proves that this theory model is true, and can be used in practical NC machining,and it is important to shorten product developing cycle,to improve product quality and to bring down cost.
