Abstract

Investigation on the identification of the motion error sources of NC- machine tools are of significance for the adjustment and control of the working accuracy of NC-machine tools. It is one of the main directions of machine tool research. In this paper, the mathmatical models of typical motion error sources of NC- machine tools are estabilished and their frequency-domain characteristics are detailed according to the circular interpolation rule and motion error forming mechanism. Based on these the frequency- domain identifying method of the motion error sources of Nc-machine tools is developed. Some examples of computer simulation and experiments are given to verify the efficiency and reliability of this method.
