High-precision CNC machine tools are widely used in automated production lines. However, due to inherent errors, production accuracy cannot reach the ideal level. To improve production efficiency and product quality, researching error compensation technology for CNC machine tools is particularly important. This paper mainly discusses the sources of errors in high-precision CNC machine tools within automated production lines and their compensation methods. By analyzing geometric errors, thermal errors, and dynamic errors of the machine tools, application schemes for model-based error compensation and sensor feedback control technologies are proposed. According to the requirements of actual production lines, an efficient error compensation system is designed, and its effectiveness in improving accuracy is experimentally verified. After implementing this error compensation technology, the machining accuracy of the machine tools is significantly enhanced, and production efficiency is considerably improved. This paper provides strong technical support and theoretical basis for the application of high-precision CNC machine tools in automated production lines.
