Drawing the outside edge of the tool in a circle, dropping the plug in the middle most of the time, with z feed rates of about 10 thou per trip around the circle. Panel is soft alu, about 80 thou thick. The subroutine used: ( arguments passed are #1 tool_rad, #2 holerad #3 xloc, #4 yloc, #5 feed rate) o130 SUB G40 F#5 (feed rate) ( MAKE SURE IT CLEARS ) G0 Z#<_ZUP> ( clear work) ( go to center of hole ) G0 X#3 Y#4 ( drop tool close to work) G0 Z0.02 G1 F#5 X[#3 + #2 - #1] ( goto where edge of holestarts ) G3 I[-#2 + #1] J-0.000 Z#<_ZDN> P12 (I've had as low as 8 for the P) G1 F5 x#3 Y#4 ( back to center of hole slow as full depth cut in case plug still there) G0 Z#<_ZUP> (back to clear) o130 ENDSUB ZUP is about 40 thou above work, ZDN is about 30 thou into the spoil board. Cherry in this instance, came from the scrap pile behind the chop saw. [...] Thanks Stuart.
