摘 要 机械零件的整个产生过程包括设计计算、工艺编制、生产加工等多道工序，其中工艺编制灵活多样，一个零件的加工过程可有多种工艺，其编制因人而异所以各不相同，一套好的工艺过程可以获得较好的加工精度、运用较少的时间、并能使操作简便，省时省力提高劳动生产率，获得最大经济效益，所以工艺编制过程在整个制造过程中具有尤为重要的作用，本课题就是关于兰州机车厂零件轴箱体的工艺过程编制、以及制造加工过程的分析研究。 本工艺过程主要包括： (1)每道工序的安排与设计，主要步骤和内容： 在分析了被加工工件的结构和精度要求之后，详细制订了零件加工整体工艺路线和粗精镗、铣工序加工工艺流程（包括工件定位、加紧、加工刀具的选择、切削用量的确定、切削力与切削功率的确定。） (2)每道工序的切削用量、加工余量、的计算。 (3)查找工艺手册、金属切削手册的查找与确定。及每道工序的执行过程中所需的夹具的使用。 ABSTRACT The entire production process of mechanical parts including multichannel working procedure such as design calculation, and technology prepared, and production processing and so on, Which technology prepared is flexible and diverse, processing process of a parts can has multiple technology, its preparation varies from person, so all does not same, a good of technology process can get better of processing precision, and using less of time, and can makes operations easy, Save time and effort to improve productivity, get maximum economic benefits, so technology prepared process in entire manufacturing process has particularly important role, this topics is on technology process prepared, and analysis research of manufacturing processing process of Lanzhou locomotive factory parts axis box. This process includes: (1) Arrangement and design of each process, the main steps and content: analysis of structure by machining and precision requirements, elaboration of parts processing entire route and coarse-fine boring, milling processes machining process (including the work piece positioning, step up, machine tool cutting force and determination of selection, cutting, cutting power to determine.), (2) Calculation of cutting, machining allowance of each process. (3) Find technology Handbook, Handbook of metal-cutting, determine cutting parameters and each process in the process of implementing the fixture that you want to use.
