  1. 典型零件编程与加工实例 • 综合实例1 • 编制如图所示零件的加工程序,材料为45钢,棒料直径为¢40mm。

  2. 1.刀具设置: 粗车外圆车刀为1号刀; 宽4mm切槽刀为2号刀; 60°螺纹刀为3号刀; 精车外园车刀为4号。 2. 工艺路线 (1) 棒料伸出卡盘外约85mm,找正后夹紧; (2) 用1号刀,采用G71进行轮廓循环粗加工; (3) 用2号刀,进行切槽加工; (4)用4号刀,采用G70进行轮廓精加工 (5) 用3号刀,采用G92进行螺纹循环加工; (6) 用2号刀切下零件。 相关计算 螺纹总切深:h=0.6495P=(0.6495×2)mm=1.299mm 零件加工 (1) 手动加工:端面、外圆(便于对刀) (2) 对刀,将工件坐标原点设在工件右端面的中心上 (3) 确定其余刀具相对基准刀具的刀补 (4) 将刀具移至安全位置,进行程序校验,确定程序编制是否有误 (5) 零件加工
