ABSTRACT
At present, numerical control machines have undergone a rapid development phase and contributed significantly to the industry. In order to utilize the numerical control machine more efficiently in the monumental industry, research on the actual error and feedback of the controller is needed to increase the precision and working efficiency. Through the research of a four-axis numerical control machine in engraving, error analysis of numerical control, and optimization of electromechanical parameters, a system error model was built to test and adjust the error in order to realize the high precision and efficiency engraving. Meanwhile, for the four-axis numerical control (CNC) machine tool with three axes using a linear motor to control, the accuracy of speed can be improved. A discussion on the overall control and accurate control research for the numerical control machine tool of the linear motor type selection and design is presented in this paper. Finally yet importantly, it optimizes the algorithm of real action of the electromechanical system and calculates feedback error to adjust the real engraving position and the digital position.
