Abstract
CNC machining technology as the core of modern manufacturing industry, its processing efficiency and precision directly determine the quality and cost of products. In the process of NC machining, the planning and optimization of tool path is the key link to improve machining efficiency, reduce material waste and ensure machining accuracy. This paper focuses on the research of tool path optimization and simulation technology in CNC machining, aiming to achieve efficient and accurate planning of tool path through advanced algorithms and simulation means, and then improve the overall performance of CNC machining. The importance of tool path optimization in NC machining is analyzed in this paper. The tool path not only affects the machining time, cutting force, tool wear and other economic indicators, but also directly relates to the roughness of the machined surface, shape accuracy and other quality parameters. Therefore, reasonable optimization of tool path is an important way to improve the performance of CNC machining. The key techniques of tool path optimization are discussed in this paper. On the one hand, advanced optimization algorithms are introduced, such as genetic algorithm, particle swarm optimization, etc., through mathematical modeling and algorithm solving, the global search and iterative optimization of the tool path are carried out to find the optimal or approximately optimal tool path. On the other hand, according to the specific characteristics of CNC machining, the algorithm is improved, such as considering the dynamic characteristics of the machine tool, the material characteristics of the tool, the material characteristics of the workpiece and other factors, in order to improve the practicality and reliability of the optimization results. Simulation technology plays an important role in the process of tool path optimization. In this paper, a simulation platform based on CAD/CAM software is used to simulate the optimized tool path. Through simulation, we can intuitively observe the moving path of the tool, cutting process and machining results, and verify the rationality and effectiveness of the optimization scheme. At the same time, simulation technology can also help identify potential problems and risks, and provide guidance for further optimization. This paper summarizes the research achievements and application prospects of tool path optimization and simulation in NC machining. By optimizing the tool path, not only the efficiency and precision of NC machining are significantly improved, but also the production cost and resource consumption are reduced. With the continuous development of intelligent manufacturing technology, tool path optimization and simulation technology will be widely used in more fields, providing strong support for the transformation and upgrading of the manufacturing industry.
