【優(yōu)秀畢設(shè)】減速機殼加工工藝及夾具設(shè)計

1、內(nèi)容摘要：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
