摘要：
Modern manufacturing technology has put forward a 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 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 a method for evaluating the positioning accuracy under different dynamic conditions using a laser interferometer on a moving bridge type CMM is designed and analyzed, which might be utilized to realize dynamic error compensation.
