摘要
Modern manufacturing technology has put forward more exacting demand of speed and accuracy on Coordinate Measuring Machines (CMMs). However, with the increase of speed, the dynamic accuracy will decrease since dynamic errors will have a great impact on the accuracy and act as a barrier to the measuring cycle time. In this paper, the influence of velocity parameters on dynamic performance of CMMs is studied. The main dynamic error sources of CMMs are identified and analyzed in detail. Different parameters, which influence the dynamic probe errors, are tested. Finally, a method for evaluating the positioning accuracy under different dynamic conditions using a laser interferometer is designed and analyzed.
