加工中心编程实例
【例6-10】 在加工中心上加工图6-31所示的壳体零件,材料HT200。零件底面、圆孔及孔止口面已加工完成,现要求:铣顶面保证 尺寸, Ra3.2m。铣槽 , Ra6.3m,一次加工完成。钻攻4M10螺纹孔及孔口倒角。
该零件以底面孔和圆孔为主定位面,侧面采用定位螺钉为辅助定位,圆孔止口面为夹紧面。一次装夹后完成所有的加工内容。加工工艺与刀具如表2-32、表2-33。 工件坐标系设在工件中心,且离工件底面上方70.1mm处。槽中心线各基点的坐标为:a(60,87)、b(102.77,20.52)、c(63.67,-65.34)、d(30,-87)、e(-30,-87)、f(-63.67,-65.34)、g(-102.77,20.52)、h(-60,87)。
