The high precision step control of CNC machine tool is the inevitable trend of the development of the mechanical motion control system, and it is also an important part of the modem industrial field. Due to the lack of accuracy of traditional NC machine tools, it is easy to cause quality defects. Therefore, the design of high-precision step control system of CNC machine tools has gradually become a research hotspot. First, the improved step control model and the more professional design of the drive system and control scheme. Secondly,in order to improve the performance of CNC machine tools and ensure the precision of the control model, the motion control system is designed and developed based on the reliability theory. In order to obtain the control system with better network performance and control performance, a stepper motor network control system is designed and the software configuration is carried out. Finally ,through the simulation experiment proved that the high precision CNC machine stepper control model not only has a relatively low cost advantage and strong load capacity, can maintain accurate and stable running effect, better than traditional machine performance. The test results show that the reliability of the system model can reach 97.89% , which fully meets the design requirements.
