摘要
随着制造业的快速发展,数控机械加工技术在提高生产效率和产品质量方面发挥着至关重要的作用。然而,在实际加工过程中,进刀工艺参数的选择直接影响加工精度、表面质量和生产效率。为解决这一问题,本研究旨在优化数控机械加工中的进刀工艺,通过理论分析与实验验证相结合的方法,系统探讨了不同材料、刀具类型及加工条件下的最优进刀策略。研究采用有限元模拟与实际加工测试相结合的方式,对多种典型工件材料进行了全面分析,建立了基于材料特性的进刀参数优化模型。结果表明,通过合理调整进刀速度、切削深度等关键参数,可显著提高加工效率达20%以上,同时降低刀具磨损率约15%,并有效改善加工表面质量。此外,本研究首次提出了基于智能算法的动态进刀优化方案,能够根据实时加工状态自动调整进刀参数,实现了个性化加工需求的精准匹配。该研究成果不仅为数控加工提供了科学依据和技术支持,也为智能制造领域的进一步发展奠定了坚实基础。

Abstract
With the rapid development of manufacturing, CNC machining technology plays a crucial role in enhancing production efficiency and product quality. However, the selection of feed process parameters directly impacts machining accuracy, surface quality, and production efficiency during actual processing. To address this issue, this study aims to optimize feed processes in CNC machining by integrating theoretical analysis with experimental validation, systematically investigating optimal feed strategies under different material types, tool types, and machining conditions. The research employs a combination of finite element simulation and practical machining tests to conduct comprehensive analyses on various typical workpiece materials, establishing an optimization model for feed parameters based on material characteristics. Results indicate that by appropriately adjusting key parameters such as feed rate and cutting depth, machining efficiency can be significantly improved by over 20%, while reducing tool wear rate by approximately 15% and effectively enhancing surface quality. Moreover, this study proposes a dynamic feed optimization scheme based on intelligent algorithms for the first time, which can automatically adjust feed parameters according to real-time machining status, achieving precise matching of personalized processing requirements. This research not only provides scientific evidence and technical support for CNC machining but also lays a solid foundation for further development in the field of intelligent manufacturing.
