1、一、零件銑削加工工藝分析1. 零件工藝分析 零件材料為硬鋁ly12,毛坯已加工好，尺寸（長寬高）為140mm140 mm30 mm，單件生產(chǎn)零件材料為硬鋁，切削加工性能良好。加工分粗、精加工兩個階段進(jìn)行，以保證尺寸公差及表面粗糙度的要求。同時(shí)用底面定位，以保證垂直度要求。2. 確定裝夾方案該零件外形規(guī)則，因此在加工各表面及孔時(shí)選用平口虎鉗夾緊。以底面和側(cè)面定位，用等高墊鐵墊起，注意墊塊應(yīng)避開孔的位置，在平口虎鉗的旁邊安置一個定位擋塊，以起工件定位作用。3. 確定加工順序及走刀路線加工順序按先面后孔、先粗后精的原則確定。先加工凸臺輪廓，再加工孔，然后加工凹槽。為了保證加工精度，各輪廓表面的粗、精

2、加工應(yīng)分開。走刀路線包括平面進(jìn)給和深度進(jìn)給兩部分。平面進(jìn)給時(shí)，外輪廓切削刀具從輪廓外延切線方向切入、切出，內(nèi)凹槽輪廓從過渡圓弧切入切出。為了保證表面質(zhì)量，均采用順銑方式分層環(huán)形銑削。深度進(jìn)給采用螺旋下刀方式達(dá)到既定深度。4.刀具的選擇根據(jù)零件的材料和結(jié)構(gòu)特點(diǎn)，采用高速鋼立銑刀。所選刀具及其加工表面見表1-1數(shù)控加工刀具卡片表1 零件數(shù)控加工刀具卡片序號刀具號刀具加工表面?zhèn)渥?規(guī)格名稱數(shù)量刀長/mm1t0112mm高速鋼立銑刀190粗加工凸臺2t0212mm高速鋼立銑刀190精加工凸臺5.切削用量的選擇凸臺、凹槽的粗加工在平面進(jìn)給和深度進(jìn)給方向都應(yīng)分層銑削，銑削時(shí)每層的側(cè)吃刀量和背吃刀量都選為3
