The Influence of Blanking Process by Superimposing Ultrasonic Vibrations
The application of ultrasonic vibrations superimposed on wire drawing, deep drawing, upsetting and rolling has been developed in the literature before. Few attempts have ever been made to develop the application of the ultrasonic vibration to blanking process. This paper reports an investigation into the effects of the superimposed ultrasonic vibrations of the punch during the blanking process by experimental design and response surface methodology. The effects of the ultrasonic vibration on the punch load and edge profile are systematically studied. The results show ultrasonic vibrations can decrease the punch load and improve the quality of edge profile.
