Chip Breaking instead of full retract peck drilling

[weaston]

Does anyone know if Solidcam has the drilling option of chip breaking instead of peck drilling? Chip breaking cycle pauses the feed at specified depth intervals instead of retracting all the way out of the hole at each depth interval.

If this option is available, how do I activate it?

Thanks

Yes, you can do chip breaking. What you do is edit your post processor. First the MAC file and there you add a line to drill cycles reading

drill_type = Chipbreak Peck Y

then in the GPP file, to the "@drill" routine, add something some code to format the G code eg (presuming it is FANUC)

if drill_type eq "Chipbreak" then
{nl, "G73 X"xpos" Y"ypos" Q"peck" Z"z_depth}
endif

Have a look in the GPP tool manual, it has it all in there.
