楔铁块零件的数控工艺 专 业：机械设计与制造 学 号： 学 生： 指导教师： 摘要：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。而对于数控加工,无论是手工编程还是自动编程，在编程前都要对所加工的零件进行工艺分析，拟定加工方案，选择合适的刀具，确定切削用量，对一些工艺问题(如对刀点、加工路线等)也需做一些处理。并在加工过程掌握控制精度的方法,才能加工出合格的产品。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：工艺分析；加工方案；进给路线；控制尺寸； The numerical control technology of the wedge iron parts Specialty： Student Number： Student： Supervisor： With the continuous development of numerical control technology and application field expands, nc machining technology to the national economy and peoples livelihood some important industry (IT, automobile, light industry, medical, etc.) is playing a more and more important role in the development, because the efficiency, quality is the main part of the advanced manufacturing technology. High speed and high precision processing technology can greatly improve efficiency, improve the quality and grade of products, shorten production cycle and enhance market competition ability. For the nc machining, manual programming or automatic programming before will be made of parts manufactured by technology analysis, drafting processing scheme, choosing the appropriate cutting tool and cutting parameter is determined, to some process problems (such as the cutting point, processing route etc.) also need to do some processing. And master the methods of control accuracy in machining process, can produce qualified products.In this paper, according to the characteristics of the nc machine tool, in view of the specific parts, process analysis, scheme of equipment, cutting tool and cutting parameter selection, determine the processing order and processing route, the nc machining programming. Through the whole process of the process, fully embodies the nc equipment
