典型零件的加工工艺
本文是对典型零件加工技术的应用及数控加工的工艺性分
析，主要是对零件图的分析、毛坯的选择、零件的装夹、工艺路线的制订、刀具的选择、切削用量的确定、数控加工工艺文件的填写、数控加工程序的编写。选择正确的加工方法，设计合理的加工工艺过程，充分发挥数控加工的优质、高效、低成本的特点。还重点对配合零件的加工艺进行了分析，最后对零件自检数据进行分析，和加工的结果分析。

Abstract
This is a typical the kind of parts of the application processing and manufacturing process of analysis nc, in particular parts of the analysis, blank choice, parts with or process of drafting, the choice of the cutting tool and the determination of usage processing document,nc nc processing procedures in and write. Correct process, design and production process, full nc of quality and efficiency, low cost. also key features of the parts of the process was analysed and finally, data analysis self-inspection parts, and processing of the results of
analysis.
