    Exclamation G87 wrap drilling or cross drilling

    Hey guys. I'm having hell with wrap drilling in my doosan puma sy.

    I can't get the drill to rise up out off the hole before it moves to the next.
    Can any body give me a sample program?

    mine is like this

    Z_____ C______
    G87 X.800 R0.0 P5000 F6.0
    Z_____ C______
    Z_____ C______
    Z_____ C______
    G80

    I am wrap drilling on .850 diameter stock.
    I only need to go about .020 to .030 deep.
    What am I doing wrong?

    You could always move your start point (R-Plane?) up 0.1 and program an R-0.1 so it will clear the part. Remember you'll have to repeat the P in every block you want a dwell.
