精车如图所示的零件。
工件的加工顺序为：
normal style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%"> (1)用3号刀切削工件的外轮廓自右向左加工，其加工路线为：
normal style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%"> 倒角>车Φ24mm外圆>车锥面Φ车Φ45mm外圆>车R55mm圆弧>车Φ40mm外圆>车R44mm圆弧>车R20mn圆弧>车Φ30mm外圆>车端面>倒角>车Φ50mm外圆>车端面。
normal style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%"> (2)用2号刀车槽。
normal style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%"> (3)用4号刀车螺纹，用螺纹循环指令切削M24X1.5螺纹。
normal style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%"> 工件坐标系如图中所示。
normal style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%"> 现以3号刀为基准刀，并测得3号刀与其他两把刀的位置偏差作为刀具位置补偿值输入到相应的存储器中。
normal style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px; LINE-HEIGHT: 150%"> 设定：2号刀位装夹车槽刀 3号刀位装夹精车刀 4号刀位装夹螺纹刀
