In this cycle bore a hole precisely. When tool is reach at bottom of hole , the spindle is stop and tool is shift from machining position and retract .Tool offset in canned cycle mode is ignored. Here we have the Spambot promoting his web site, still getting it wrong again. G74, specified in your program is Left/Hand Tapping, not a Boring Cycle. First rule of CNC Programming; check your code. Posing it here without checking it, is tantamount to loading the program in the machine, pressing the Cycle Start and hope that it works.

With regards to the Q address for the shift amount, this is control specific; oh. you didn't know that.

This guy is a Spambot, dredging up ancient Posts to promote his own web site.

If you're going to promote yourself as some type of expert, you should at least explain that your program is going to cut a Left Hand Thread; or weren't you aware of that?

Having the minimum DOC clamped at the same value as the first pass value somewhat negates the advantage of the G76 Cycle; or weren't you aware of that?

Nothing from your example program would entice me to visit your web site.
