Dynamic characteristics of the system have been given more and more attention so as to improve the retention and reliability of machining accuracy. Research has shown that dynamic performance of the feed drive mechanism has significant impact on the processing quality and efficiency of CNC. This paper mainly focuses on the DCG which realizes its motion on the basis of a pair of lead screw. The dynamic performance of the DCG was analyzed by the method of finite element analysis. DCG structure and the key design parameters of the rail joint surface have been studied to find out the influence on its dynamic characteristics. These researches provided a basis for the realization of the CNC feed motion of high-speed and high-precision. Besides, it is also possible to improve the overall performance of CNC machine tools.
