Abstract

Modern manufacturing increasingly places a high requirement on the speed and accuracy of Coordinate Measuring Machines (CMMs). Measuring speed has become one of the key factors in evaluating the performance of CMMs. In high speed measuring, dynamic error will have a greater influence on accuracy. This paper tests the dynamic error of CMM's measuring system under different measuring positions and speeds using the dual frequency laser interferometer. Based on measured data, the modeling of synthetic dynamic errors is set up adopting the dual linear returns method. Comparing with the measured data, the relative error of modeling is between 15% to 20%, the returns equation is prominent at α=0.01 level, verified by "F". Based on the modeling of synthetic dynamic errors under different measuring positions and speeds, the measuring system dynamic error of CMMs is corrected and reduced.
