Abstract：

In workpiece punching process, as the hybriddriven servo press is different from the general servo press, it can solve the problem of power limited due to two motors, but the velocity error of punch motion becomes more complex, the punch displacement curve is not easily modified, and the machining accuracy is difficult to be achieved. On the basis of the analysis of the velocity error, a mathematical model of velocity loss was established, and a compensation strategy of velocity error was put forward. Moreover, an experiment including four type of punching materials and sizes was tested, and the experimental results were compared with the best compensation value of the model calculated. The verified results show that the material properties and sizes of the workpiece, the initial velocity of the punch affect the velocity loss, and the model of velocity loss are more consistent with the experimental results.
