We have quite a few questions about having rigid tapping on certain lathes.
Is there really any difference, except convenience, to make up your own cycle using G32 or G33?
I can remember way back, I was training a small shop in Florence, SC, he had a Wasino Gangturn and the job we set up had a 1/4-20 tap in Alum.
There was no Rigid tapping in those days and we programmed:
G0 X0 Z.2*
G32 Z-.7 F.05 M5*
G32 Z.2 F.05 M4*
G0 X2.0 Z2.0*
etc.
His machine read the M5 at the end of the line, you would have to check how your machine is set up,
We held the tap solid, no floating tap holder.
Since then, I have than this on a number of different lathes, it seems to be just like rigid tapping.
All lathes have a sort of resolver that coordinates the RPM with the feedrate, mills do not have this, so Rigid tapping is a somewhat costly options.
