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。
关键词:
工序,工位,工步,加工余量,定位方案,夹紧力
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.
Keyword:
The process, worker one, worker's step , the surplus of processing, orient the scheme , clamp strength
