Spindle wear of CNC machine affects the working efficiency of the machine. To solve this problem, the reasons for the generation of CNC machine tool equipment wear is analyzed, the system's hardware modules and software modules are designed and implemented in accordance with the system requirements. Parameters such as input and output power, spindle speed of CNC machine tool equipment are acquired by the sensor circuit. After a comprehensive analysis of the data, system software combined with neural network model displays the test results on the LCD screen, real-time output of CNC machine tool equipment operating status and the spindle wear. Thus the operation of CNC machine is ensured and equipment failure is avoided. Through the system test, indicating that the proposed system can real-time output the monitor results of spindle wear of CNC machine tool equipment, and has high measurement accuracy for the main parameters such as power and efficiency of the equipment.

Synthetic error of CNC machine tool, mainly including geometric error and thermal error, is generally affected by many factors. And temperatures that include environment temperature and temperature asymmetry of machine tool are most important factor. Aiming at geometric error and thermal error mainly, this paper proposed a real-time synthetic error compensation solution for CNC machine tool based on Differential Resolver Function (DRF). The principle of this solution is offsetting the origin of workpiece coordinate system when implementing the NC code in machine tool. After real-timely collecting machine tool coordinates position and thermal key points’ temperatures, synthetic errors are calculated by the synthetic model that is beforehand constructed and stored in compensation equipment, and then the pulses that represent coordinate system origin offsetting value are generated and sent into NC system by DRF to realize synthetic error compensation of CNC machine tool.
