支架零件的工艺规程及钻夹具设计
摘要
本次设计课题是支架零件的机械加工工艺及夹具设计，内容涉及了机械制造工艺及机床夹具设计、金属切削机床、公差配合与测量等多方面的知识。
在生产过程中，使生产对象（原材料，毛坯，零件或总成等）的质和量的状态发生直接变化的过程叫工艺过程，如毛坯制造，机械加工，热处理，装配等都称之为工艺过程。在制定工艺过程中，要确定各工序的安装工位和该工序需要的工步，加工该工序的机车及机床的进给量，切削深度，主轴转速和切削速度，该工序的夹具，刀具及量具，还有走刀次数和走刀长度，最后计算该工序的基本时间，辅助时间和工作地服务时间。

Abstract
This design topic is the machining process and fixture design contents of bracket related to mechanical manufacturing process and fixture design, metal cutting machine tool, tolerance and measurement and other aspects of knowledge.
Enable producing the target in process of production(raw materials, the blank, state of quality and quantity on part become always) take place direct course of change ask craft course, if the blank is made, machining, heat treatment, assemble etc. and call it the craft course. In the course of making the craft, is it confirm every erector location andworker step that process need this of process towant, the locomotive of processing, this process, and the entering the giving amount of the lathe, cut depth, the rotational speed of the main shaft and speed of cutting, the jig of this process, the cutter and measuring tool, a one hundred sheets of number of times still leaves and a one hundred sheets of length leaves, calculate basic time of this process, auxiliary time and service time of place ofworking finally.
