This paper proposes a modular multifunction punch AID for the teaching practice of microlecture for engineering training .Starting from the mathematical model of punching process ,the kinetic characteristic of crank‐slider mechanism has been analyzed . The drive scheme is studied after the fatigue performance of mechanism has been validated theoretically .Through the use of PID algorithm of integration separation mode , it is solved that patterns pressed on the strip are uneven .The results of application show that this teaching aid has reasonable structure and great practicality for online interactive teaching .
