Can I change the retract between pecks of a G73 cycle?

I would like to know if there is a way to change the value of the rapid clearance of .100 between pecks in the chip-break peck-drilling cycle (G73). We are drilling through plastic, copper and stainless steel tubing. In order to keep drills from breaking (we are drilling (380) #30 drill holes .625 deep.) We can only drill at .7 Feed using a 'Q' peck of .03. Therefore with the .100 Rapid Clearance we are wasting a lot of time drilling air. Any help would be greatly appreciated. Thank you, Herb Jeffery

Response:

Yes - if it's a Fanuc control. There is a parameter that controls the retract in a G73 cycle. Unfortunately, the parameter number varies based upon Fanuc model, so I can't tell you what the number is. If you look in your Fanuc operators manual in the G73 description, you'll find the related parameter as well as how it is set. It can be set to any value, but I'd recommend about 0.003 inch or so - just enough to let the chip break.
