    Default Bolt Hole Circle Pattern Problem FADAl CNC Mill 88

    I Am trying to drill hole pattern with below specifications


    I used these codes but it doesn't work properly it seems center of the holes changes for each pattern cycle.

    G81 G99 R0+0 Z-10 F10
    L9304 R0+.1 R1-25 R2-90
    G80
    G90
    G0 X28.75 Y49.8
    G81 G99 R0+0 Z-10 F10
    L9304 R0+.1 R1-57.5 R2-30

    (angle between 20 Dia. holes would be 32.73,dimensions mm)

    what would be the best way to program fadal cnc 88 for this type of action ?

    I'm not sure where you got your numbers from, but I came up with these using the pattern center for all the locations. I didn't verify this in a control, but it should be in the ballpark.
