Notes:
This paper introduces a novel controllable mechanical metal forming press, which is a2-DOF planar mechanism driven by a large constant speed motor and a small servomotor. The constant speed motor provides the main power while the servomotor tunes the trajectory and velocity of the punch in order to realize the controlled punch motion. The new press needs high accuracy, repeatability and resolution to guarantee the controlled punch motion. Improving manufacturing andassembly process could help it, but sometimes is very difficult and not feasible. Therefore parameter calibration has a significant effect on the accuracy, repeatability and resolution of the press. In this work, a simple parameter calibration method is presented without using complex and precise metrology system. Experiment results indicate that this kind of calibration method is fast, easy,accurate and cost effective
