Analysis of Blanking Vibration Using Screw Drive Servo Press and Prediction of Optimum Blanking Condition for Vibration Restraint

Abstract

In this study, we propose the most suitable condition for blanking using a screw drive servo press. The conditions do not increase blanking vibration. Moreover, there is no wasted time during blanking. The screw drive servo press has a highly precise slide location system. This highly precise machine is realized by including a feedback control system of the slide position. However there is a problem that blanking vibration is increased by incorporating this system. When blanking speed is fast, this problem occurs. Thus, we studied the relationship between the control response and blanking vibration of the screw drive servo press to solve this problem. In this study, we carried out a simulation and an experiment. As a result of this study, we found the most suitable condition for low-speed blanking using the screw drive servo press to be a blanking time equal to the disturbance settling time of the feedback control system.
