中央广播电视大学数控技术 专业毕业论文毕业论文题目：数控车削加工中的刀具选择姓 名： 项阳 学 号：509417126班 级：06 五年制数控 指导老师与职称： 周文兵 2011 年 06 月 01 日中 文 摘 要理想的加工程序不仅应保证加工出符合图样的合格工件，同时应能使数控机床的功能得到合理的应用和充分的发挥。数控机床是一种高效率的自动化设备，它的效率高于普通机床的 2～3 倍，要充分发挥数控机床的这一特点，必须在编程之前对工件进行工艺分析，根据具体条件，选择经济、合理的工艺方案。数控加工工艺考虑不周是影响数控机床加工质量、生产效率与加工成本的重要因素。本文从生产实践出发，探讨和总结一些数控车削过程中的工艺问题。 英 文 摘 要The ideal processing procedure should not only guarantee the machining for the workpiece, meanwhile the pattern should be qualified to make numerically-controlled machine tool's function get reasonable application and sufficient play. Nc machine is a kind of efficient automation equipment, it is more efficient than the conventional machine tools of 2 ~ 3 times, to give full play to the characteristics of CNC programming, must be in process analysis of workpiece before, according to the specific conditions, the choice of economic and reasonable process scheme. Nc machining process thoughtfulness is the effect of nc machine tools machining quality, production efficiency and machining cost of important factor. This article from the production practice, discusses and summarizes some of the numerical control turning process process problems. 关 键 词（Keywords）：工序划分，刀具选择，生产实践目 录第一章 前言.....................................................3第二章 数控机床的组成和工作原理.................................42.1 孔加工刀具类..............................................42.2 数控铣刀类................................................42.3 拉削刀具类................................................52.4 其它刀具...........
