三坐标测量机动态误差补偿的研究

A Study of Compensation for Dynamic Errors of CMMS

本文研究了三坐标测量机在高速测量过程中的动态误差。针对一移动桥式三坐标测量机，分析了其动态误差的产生原因，建立了动态误差的数学模型，对动态误差进行了全面的测量和补偿。实验证明动态误差具有一定的重复性，可用软件补偿，从而提高三坐标测量机快速测量的精度。

The dynamic errors of three coordinates measuring machine during fast probing are studied in this paper.For a moving bridge machine under investigation,the dynamic error sources are analyzed,a model for dyna mic error is made and the errors are measured completely.The test results show that the repeatability of dynamic errors is good.The errors can be compensated by software method to enhance the accuracy of the CMMs.
