典型零件的數(shù)控編程
編制如圖所示零件的加工程序
材料為45鋼,棒直徑為80mm,該零件采用棒料毛坯,由于加工余量大,在外圓精車前采用粗車循環(huán)指令去除大部分毛坯余量,留有單邊0.25mm余量。
1、刀具設(shè)置
選擇外圓粗車刀為1號(hào)刀,外圓精車刀為2號(hào)刀,割槽刀(寬2mm)為3號(hào)刀,60度硬質(zhì)合金螺紋刀為4號(hào)刀。
2、 工藝路線
1) 把長(zhǎng)軸在車床上找正位置后進(jìn)行夾緊定位;
2) 用外圓粗車刀從右到左粗車工件各面,分別留0.2mm精車余量;
3) 然后用外圓精車刀從右到左精車各面到尺寸要求;
4) 換螺紋車刀車螺紋;
5) 割退刀槽,并用割槽刀右刀尖倒出C1倒角;
6) 程序結(jié)束。
