Abstract：

Simultaneously manufacturing the punch and matrix cutting is widely used in die industry.An appropriate method of making a gradient wire cutting is given through an applied example and gradient calculation formula is predigested in contrast with the old ones.In addition,the working technics and procedure of the product are analysed and experiential formula of interval between punch and matrix are given.In order to reduce manufacturing progress,a measure how to cut inward oriented hole is introduced.The shape is identical and interval is reasonable between the punch and matrix after cutting simultaneously.Correspondingly,it can reduce manufacturing material,shorten product cycle and save product cost.
