郑州科技学院 专科毕业设计（论文） 题目：轴类零件数控车削工艺分析及数控加工编程 轴类零件数控车削工艺分析及数控加工编程 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题。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）也需要一些处理。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，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 Shaft parts CNC turning technology analysis and NC programming Abstract With the continuous development of numerical control technology and applications expand, CNC machining technology on the economy of a number of important sectors (IT, automotive, light industrial, medical, etc.) play an increasingly important role, since the efficiency, quality is the theme of advanced manufacturing technology. High-speed, high-precision machining technologies can greatly enhance efficiency, improve product quality and grades, shorten the production cycle and improve market competitiveness. For NC processing, whether automatic or manual programming programming, programming before the processing of parts for process analysis, formulation and processing programmes, selecting the right tool to determine the cutting parameters, on a number of technology issues (such as on the knife point, processing line, etc.) also needs some work. And process mastery control precision, to processing the qualified product. This article in accordance with the characteristics of CNC machine tools, tailored to specific parts, a process of analysis, determination of tooling programme, tool and cutting parameters selection, determine the order and processing lines for processing, the processing efficiency, simplify processes, and other benefits.
