内容摘要
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，加工该工序的机床及机床的进给量，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。
由于其加工批量很大，专用夹具设计中参考了许多成熟的结构，本设计结构简单、操作方便，使用了大量的标准元件，大大缩短了本工序的辅助时间，一定程度上提高了劳动生产率，减轻了工人的劳动强度。

Abstract
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 and worker step that process need this of process to want, 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 of working finally.Because the processing batch to be very big, in the design has referred to many mature structures, this design structure is simple, the ease of operation, has used the massive standard components, reduced this working procedure non-cutting time greatly, in the certain extent raised the labor productivity, reduced worker's labor intensity.
 
Keyword:
The process, worker one, worker's step , the surplus of processing, orient the scheme , clamp strength, Unit clamp .
