example of tapping cycle for an O-T control
Hi I want to tap some parts on my puma 10-HC with a fanuc O-T control
303 stainless 4-40 tap
can anyone give me examples of the canned cycle used? I believe its a G84 but Im not sure on how its setup
if not I can always do it the long hand way
thanks in advance

Are we talking a single tapped hole on the c/line along the Z axis?

I don't know if that's a lathe or a mill, but the G84 cycle is pretty simple. Assume 32 threads per inch.
G84 Xx.x Yx.x Z-.35 F32.0
It would be similar for a lathe, though you'd eliminate the X-Y positions and use F0.032 (feed in inches per revolution.)
You'd need a compression-tension holder unless the machine has rigid tapping option. If it has that, you might add M29 into a line before the G84.
If it is a mill and you want more holes, you just give a line with the X-Y positions for each hole. The G84 is modal and repeat the Z and the cycle for every position until it sees the G80 cancel code.
