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、航天等)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。

Abstract
Along with numerical control technology unceasing development and application domain expansion, nc machining technology of national economy and the people's livelihood some important industry (IT, automobile, light industry, medical treatment, the development of playing a more and more important role, because the efficiency, quality is the subject of advanced manufacturing technology. High speed, high precision machining technology can greatly improve the efficiency, improve the quality and grade of the products, shorten production cycle and improve the petition ability. And for nc machining, whether manual programming or automatic programming, ChengQian at all to the parts processing process analysis and processing scheme worked, choose proper tool, sure, for some cutting dosages process problems (such as the cutting point, processing of route etc) also need to do some processing. And in the process control precision of the master method, can processing of qualified products.
According to the characteristics of the numerical control machine, in specific parts of the technology, the analysis of the scheme, the scheme determination of tooling, knives and selection of cutting parameter, sure processing order and processing route, C programming. Through the whole process of the formulation of process, fully embodies the numerical control equipment in the guarantee machining precision machining efficiency, simplify the process, the advantages of the.
