Modeling and Simulation for Feed Servo System in CNC Machine Tool

Feed servo system is an important part in CNC machine tool. In order to promote CNC machine tools precision, it is particularly important to enhance the control methods research on feed servo system. In this paper, different mathematical models of CNC machine tools feed servo system in different control modes are established, and their transfer functions are obtained, also the corresponding simulation models are constructed by using Simulink tools under MATLAB environment. Through simulating, the relationship between the systems parameters and the performance of servo system are obtained, some reliable theoretical basis can be achieved for improving and enhancing CNC machine tool servo system performance. Therefore some references for the performance optimization of feed servo system in CNC machine tool are provided.
