CA6140 车床后托架加工工艺及夹具设计学生姓名：学生学号：院（系）： 机电工程学院 年级专业： 机械制造及自动化 指导教师：二〇〇六年六月摘要在生产过程中，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，尚有走刀次数和走刀长度，最终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，工艺，工步，加工余量，定位方案，夹紧力全套图纸加 153893706ABSTRACTEnable 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.Keywords：The process, worker one, worker's step , the surplus of processing, orient the scheme , clamp strength目 录摘要 IABSTRACT21CA6140 机床后托架加工工艺 31.1 CA6140 机床后托架的工艺分析 3 1.2 CA6140 机床后托架的工艺规定及工艺分析 3 1.2.1 CA6140 机床`后托架的技术规定 31.3 加工工艺过程 3 1.4 确定各表面加工方案 4 1.4.1 在选择各表面及孔的加工措施时，要综合考虑如下原因 41.4.2 ...
