轴套零件建模、加工工艺分析及数控编程
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。

Abstract: With the expansion of CNC technology continues to evolve and applications, CNC machining technology development for a number of important industries (IT, automobile, light industry, medical and other) national economy plays an increasingly important role, because the efficiency, quality is advanced main manufacturing technology. High-speed, high precision technology can greatly improve efficiency, improve product quality and grade, shorten the production cycle and enhance market competitiveness. For CNC machining, either manual or automatic programming, must be on the processing of parts before programming process analysis, formulation and processing program, select the appropriate tool to determine the amount of cutting, some process issues (such as knife-point, processing routes, etc.) also need to do some processing. And in the process take control precision approach to processing of qualified products.
Based on the characteristics of CNC machine tools, for specific parts, craft solutions were analyzed to determine the tooling solutions, tools and cutting the amount of choice to determine the processing order and processing line, CNC machining programming. Through the development process of the whole process, and fully reflects the CNC equipment to ensure accuracy, processing efficiency, streamline processes and other aspects of the advantages.
