1、底板零件的機(jī)械加工工藝規(guī)程及銑床夾具設(shè)計(jì)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(jī)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(jī)車及機(jī)床的進(jìn)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(jì)算該工序的基本時(shí)間，輔助時(shí)間和工作地服務(wù)時(shí)間。機(jī)械工業(yè)是一種基本工業(yè)形式，對于我們國家來說，它關(guān)系到國計(jì)民生的方方面面。近年來機(jī)械工業(yè)領(lǐng)域向著高精度、高質(zhì)量、高效率、低
