V-140 两段变速及V-80两段变速程式写法如下:
G90G54G00X0.Y0.M08; G43Z20.H01;
M03S2000;此S 用于主轴变至高速或低速档。 M29S800;此S为实际攻牙之转速。
G98G84R5.Z-20.F800;F=攻牙转速(800)*牙距9(1)=〉800
G80M9;
G91G28Z0.M5; M30;
注<1> M29S650=>以上主轴必须在高速档。
S650=〉以下主轴必须在低速档。 V-140=〉M03S1063=〉以上为高速档。 S1063=〉以下为低速档。 V-80=〉M03S1399=〉以上为高速档。 S1399=〉以下为低速档。
注〈2〉V-80单段的M03S800与M29S800之S相同即可。
