| Abstract: | Rapid and precision processing puts higher requests for CNC machine. Based on the second order system model of CNC machine, the relationship between some certain machine parameters (such as the bandwidth of the servo system, the sampling frequency, the position loop gain Kp factor, the speed loop gain Kv factor and the error register of the detection device)and the performance and precision of the CNC machine was specifically analyzed and concluded according the control theory. This further leads to the detailed requirements of these parameters for a CNC machine to obtain good control performance and precision, which will definitely influence the understanding and design of CNC machine to some extent. |
