I wrote a couple programs for the Okuma lathe, that we added block delete
to add an extra 'finish' cut and stop the spindle so you could measure the
diameters
and adjust the tool. It allowed you to adjust the offsets while paused and they
took
effect on the next movement of the machine. Super handy for set up.
I had another program for a shaft with a few low tolerance diameters.
The machine would not cut all of them on size, so I finished close to spec,
measured then had to edit the program to compensate. Pain in the ass.
This machine didn't have wear offsets just tool offsets. I didn't know about
the technique of using multiple tool offsets at the time.

Could use explain this line? I've read a few times and can't make it clear in
my head.
