数控铣床程序练习侧铣钻槽铣

提交人：BEATA

总结

Q. 为所示图形编写 CNC 零件程序

对于侧铣，采用速度 1200 rpm &进给 100 mm/min
对于钻孔，采用速度 1200rpm &进给 80mm/min
对于槽铣，采用速度 1200rpm &进给 120mm/min
取孔径为15mm
使用绝对坐标系。

解决方法：

操作顺序：
1 设置参考点、坐标系、刀具，给定进给和速度值
2 设置刀具半径补偿左偏
3 刀具在A，启动主轴并下刀进给（-Z方向）
4 继续进行侧铣切削，主轴停在A点
5 刀具移至参考点，对刀槽切削
6 刀具移至P，开始主轴下刀
7 继续铣槽切削，主轴停在S
8 移刀到参考点，对刀钻孔
9 移刀到P，启动主轴并进行全深度切削
10 向上移动刀具并停止主轴。
11 将刀具返回参考点。
12 程序结束

N001 G71 G90 (Set dimension type mm, set absolute co-ordinate system)
N002 G92 X-15.0 Y-15.0 Z0.0 T01 F100 S1200 (Set reference point -15, -15, 0. Tool T01 side milling tool. Feed 100mm/rev, spindle speed 1200 rpm)
N003 G41 G00 X0.0 Y0.0 Z2.0 (Cutter radius compensation left ON, move the tool at A & give clearance of 2mm before starting spindle rotation)
N004 G01 Z-15.0 M03 (Start the spindle. Move tool down i.e. at Z direction for cut with feed here M03 will execute first)
N005 G01 X0.0 Y110.0 (Go to B linearly)
