Influence of blanking distance of materials on increase in blanking vibration using screw drive servo press

In this study, we propose a suitable blanking velocity for the blanking of different materials using a screw drive servo press. Under this blanking velocity, press blanking can be carried out without causing an increase in blanking vibration. Blanking noise and vibration are causes of pollution. Mor...
