摘要
数控机床进给传动系统的设计，一般是根据系统的要求，对各个部件进行单独设计．本文按照优化设计的理论和方法，对该系统进行整体优化设计研究，以得出系统最优目标值下主要参数的选择．
When a feeding transmission system of NC machine tools is designed,its components are usually designed separately according to their specifications. In order to obtain the primary parameters of the system with the smallest rotary inertia,the design of the whole system is optimized based on the theory and methods of the optimum design.
