.
long drills i have seen simple G1 with feed rate like F3.0
.
common to have drill over 18" long vibrating and to have it enter a previously drilled hole 6" deep turning 50 rpm and F10. feed
.
once 0.1" above previous drilled hole then another M3 S300 given to change rpm and another G1 with F rate to drill hole
.
then another M3 S50 and G1 F10, to pull out of hole slow. long drill out of hole will whip or wobble bad and can even break

hello DMF_TomB what you said means using G codes, and i can program this way

i wish to use cycles, so to "feed in-out " instead of rapid, during a cycle i asked because i don't know how to do this ... and maybe i will combine "G codes" + "slow feed cycle", and results will be better than what i do now

simple way is to post it long hand. Then you can do whatever you want.

no canned cycle, all individual moves, Z down, Z up, Z down, Z up. Your cam software should have a toggle to turn canned cycles on or off.

Yes, the simple answer is to write out the drilling cycles using G1 moves instead of canned cycles, where you can specify different "F" feedrates.

It is possible to write a custom G-Code macro (canned cycle) that allows for a custom feedrate during retract, but that would require someone to develop this.

What's the machine and control? Some boring cycles have feed-out parameters (like G85) but most are simple feed-in/feed-out without an adjustment.

Edit: whoops saw this is in the Okuma subforum. This link says G85 and G86 are boring cycles (at least in milling): Okuma Mill G and M Codes - Helman CNC
