摘 要数控加工技术是以数字量编程实现控制机械或其他设备自动工作的技术。 随着数控技术的不断发展和应用领域的扩大，数控加工技术对国计民生的一些重要行业（IT、汽车、轻工、医疗等）的发展起着越来越重要的作用，因为效率、质量是先进制造技术的主体。高速、高精加工技术可极大地提高效率，提高产品的质量和档次，缩短生产周期和提高市场竞争能力。本文根据数控机床的特点，针对具体的零件，进行了工艺方案的分析，工装方案的确定，刀具和切削用量的选择，确定加工顺序和加工路线，数控加工程序编制。通过整个工艺的过程的制定，充分体现了数控设备在保证加工精度，加工效率，简化工序等方面的优势。关键词：数控加工；工艺分析；数控编程；CAD/CAMAbstractNC machining technology is based on the digital programming to control machinery or other devices to work automatically technology. Expands unceasingly along with the development of numerical control technology and applications, some of the major industries of the CNC machining technology (IT, beneficial to the people's livelihood automobile, light industry, medical etc.) plays an increasingly important role in the development, because the efficiency, quality is the subject of advanced manufacturing technology. High speed, high precision machining technology can greatly improve efficiency, improve product quality and grade, shorten the production cycle and improve the ability of market competition. The according to the characteristics of CNC machine tools, for specific parts, process analysis, determination of tooling plan, selection of cutting tools and cutting parameters determined the processing order and processing line, NC machining programming. Through the process of the whole process of the development, fully embodies the CNC equipment to ensure the machining accuracy, processing efficiency, simplify the process and other aspects of the advantages.Key words: NC machining; process analysis;...
