摘 要:
在生產(chǎn)過程中,使生產(chǎn)對象(原材料,毛坯,零件或總成等)的質(zhì)和量的狀態(tài)發(fā)生直接變化的過程叫工藝過程,如毛坯制造,機械加工,熱處理,裝配等都稱之為工藝過程。在制定工藝過程中,要確定各工序的安裝工位和該工序需要的工步,加工該工序的機車及機床的進給量,切削深度,主軸轉(zhuǎn)速和切削速度,該工序的夾具,刀具及量具,還有走刀次數(shù)和走刀長度,最后計算該工序的基本時間,輔助時間和工作地服務(wù)時間。
關(guān)鍵詞:
工序,工位,工步,加工余量,定位方案,夾緊力
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
