Punching is widely used in all aspects of daily life and production in the current. the process of rotary punch is introduced as an innovative manufacturing method . Cost of rotary punch is more cheap than press and dies, which to reduce manufacturing costs; usually no drive is required, which to access to energy saving；provide uniform repeated pattern. Rotary punch can be match to the cold roll forming production line. We work hardly to research and explore of rotary punch and kinematic, which will provided with significance of theoretical and engineering application
