Aiming at the problem that the synchronous difference between CNC motor and controller is large in the current CNC machining accuracy control method of ship mechanical parts, which leads to the decline of the stability and accuracy of CNC machining accuracy control of parts and affects the yield of high-precision parts, this paper puts forward the CNC machining accuracy control method of ship mechanical parts. In order to standardize the operation quantity of CNC equipment, the parameter data of equipment operation in the process of CNC operation are collected, the control signal of CNC equipment is optimized, and the characteristic algorithm of non-stationary mechanical characteristic signal is introduced. The corresponding number of pulse signals generated by the vibration of CNC equipment is extracted, and the motor speed control variables in the operation process of CNC equipment are calculated to optimize the motor speed control. According to the PID control logic of CNC equipment control, the control signal of the controller is checked synchronously to complete the CNC machining accuracy control of ship mechanical parts. The experimental results show that the synchronous difference between the motor and the controller is small, which can effectively improve the stability and accuracy of CNC machining accuracy control.
