Feedrate overide was Re: rotary hand encoder wheels with detent

Alan,

As a percentage of "programmed" feedrate. Typical knobs go from 0 to
200% (some to 150%) in 10% increments.

The idea is that the machinist standing at the machine may find a
better feedrate by "sound","feel" or "experience" than what is
programmed in the CAM office upstairs. So the F/R overide is adjusted
for the best cutting action aT the machine during program "proving".

A "fully proved" program SHOULD run correctly with the F/R overide at
100%.

The tough part historically has been getting these "shop floor"
changes BACK up to the programming office, so they don't have to keep
re-inventing the wheel...

Hope this helps.
