Abstract: Aiming at the vibration and noise problems brought by the processing of CNC turret punch press, the research was conducted to the action process of punching process and noise reduction schemes of CNC turret punch press, the punching process and the kinematics of the connecting rod structure were analyzed. It was proposed to realize the mute punching by reducing the punching speed and prolonging the action time of the punching force, and designing. The motion curve of the punch slider. The motion control design of the punching speed and the punching stroke of the punch of the CNC turret punch press were performed by the servo control system. The PLC program was written by using the Codesys software, the vibration and noise of CNC turret punch press before and after improvement were measured and compared by the test machine. The results indicate that this method can significantly reduce the vibration and noise caused by punching action, and the control system has high reliability, the punching effect is good, and the mute punching function can be realized.
