箱体类典型零件的数控加工工艺分析 摘要 论文首先介绍了数控机床的趋势：工序集中、高速化、高效、高精度、多功能等。从数控加工工艺基础讲起，由浅入深的分析了数控加工工艺的特点及技术要求。对典型箱体类零件的数控加工工艺分析及举例分析。 数控加工工艺是采用数控机床加工零件时所运用各种方法和技术手段的总和，应用于整个数控加工工艺过程。数控加工工艺是伴随着数控机床的产生和发展而逐步完善起来的一种应用技术，它是人们大量数控加工实践的总结。数控加工工艺是数控编程的前提和依据，没有符合实际的、科学合理的数控加工工艺，就不可能有真正可行的数控加工程序。数控编程就是将制定的数控加工工艺内容程序化。 箱体类零件的加工精度高，工艺难度较大。除了一般零件的共性外有其铣平面，铣孔，热处理特殊特点。 因此对箱体类零件的加工工艺分析对数控加工工艺方面的一个丰富的积累。 关键词：数控机床；箱体类零件；加工工艺。 Box-type parts of a typical CNC machining process analysis Abstract Paper introduces the trend of CNC machine tools: process focus, high-speed, high efficiency, high precision, multi-function, such as. From talking about the basis of numerical control processing, easy-to-digest analysis of the characteristics of CNC machining technology and technical requirements. The typical box-type parts on the CNC machining process analysisand example analysis. CNC machining process is the use of CNC machining parts by using various methods and techniques of the sum of the means applied to the entire CNC machining process. CNC machining process is accompanied by the emergence of CNC machine tools and development with a gradual improvement of application technology, it is the practice of a large number of CNC machining summary. CNC Machining NC programming process is the prerequisite and basis for, not in line with the practical, scientific and rational CNC machining process, there can be no real NC machining process possible. NC programming is to formulate the contents of the NC processing program. Box-type high-precision machining, process more difficult. In addition to the general common parts outside the plane of its milling, hole milling, heat treatment of special features. Box-type parts on the process of analysis of the aspects of CNC machining process to a rich accumulation. Keywords: CNC machine tools; box components; processing technology. 目录 第1章 概述 4 1.1 数控加工技术的发展和趋势 4 1.2 数控加工的定义 5 1.3数控加工工艺的定义 6 1.4数控加工工艺的特点 6 第2章 数控加工工艺基础 7 2.1 数控加工工艺分析 7 2.2零件图的分析审查 8 2.3零件机械加工工艺规程的制定 9 第3章
