Abstract

The instability of machining accuracy in CNC machine tools severely affects product quality and production efficiency, becoming a critical issue that the manufacturing industry urgently needs to address. This paper analyzes the main factors influencing machining accuracy during the CNC process, such as mechanical structure errors, environmental vibrations, tool wear, and fluctuations in the control system. Targeted improvement measures are proposed, including optimizing mechanical design, enhancing environmental control, selecting tools reasonably, and improving CNC system algorithms. Practical results show that these improvements effectively enhance the stability of machining accuracy and promote high-quality development in the manufacturing process.
