As a key control factor in NC machining process, the optimization of cutting parameters is of great significance for improving machining efficiency and ensuring machining quality. This paper focuses on the optimization of cutting parameters in NC machining, aiming to explore the scientific and reasonable strategy and method of cutting parameters optimization through the combination of theoretical analysis and practical application. In this paper, the basic concept and classification of CNC machining cutting parameters, including cutting speed, feed speed, cutting depth and other key parameters are described in detail. Then, the influence mechanism of cutting parameters on NC machining process is analyzed. It is pointed out that reasonable cutting parameters can effectively reduce cutting force, reduce cutting heat, improve tool life and machining surface quality. In terms of optimization strategy of cutting parameters, this paper presents a variety of optimization methods. On the one hand, by establishing the mathematical model between cutting parameters, machining quality and machining efficiency, using genetic algorithm, particle swarm algorithm and other intelligent optimization algorithms to solve, to find the best combination of cutting parameters. On the other hand, combined with practical experience and field data, the traditional optimization methods such as trial and error method and orthogonal test method are used to adjust and optimize the cutting parameters step by step. In addition, the matching relationship between cutting parameters and machine tool performance, tool material, workpiece material and other factors is discussed, and the optimization suggestions of cutting parameters for different machining scenarios are put forward. In practical applications, the optimization of cutting parameters not only improves the efficiency and quality of CNC machining, but also reduces the production cost and energy consumption. For example, in high-precision and high-demand machining fields such as aerospace and automotive manufacturing, efficient and accurate machining of complex parts is achieved by optimizing cutting parameters. At the same time, the optimization of cutting parameters also promotes the further development and popularization of CNC machining technology, and provides strong support for the transformation and upgrading of the manufacturing industry. The optimization of cutting parameters in NC machining is a complicated and important work. Through scientific and reasonable optimization strategies and methods, the efficiency and quality of CNC machining can be significantly improved, and the manufacturing industry can be promoted to the direction of intelligent and green development.
