文档介绍：I大家需求加QQ409188388为你们免费提供CA6140版的课程设计全套此为CA6140车床拔叉割断的课程设计II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,***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。关键词工序工艺定位方案IIIAbstractEnableproducingthetargetinprocessofproduction(rawmaterials,theblank,ealways)takeplacedirectcourseofchangeaskcraftcourse,iftheblankismade,machining,heattreatment,,isitconfirmeveryerectorlocationandworkerstepthatprocessneedthisofprocesstowant,otiveofprocessing,thisprocess,andtheenteringthegivingamountofthelathe,cutdepth,therotationalspeedofthemainshaftandspeedofcutting,thejigofthisprocess,thecutterandmeasuringtool,aonehundredsheetsofnumberoftimesstillleavesandaonehundredsheetsoflengthleaves,calculatebasictimeofthisprocess,.............................................................................................................................ⅠAbstract.........................................................................................................................Ⅱ第1章绪论.........................................................................................................................................................................................................................................................................................................................................................................................................................................3第2章拨叉的加工工艺规程设计..........................................................................................................................................................................................................................................................................................
