Yes. And as already said back the tool off after the final finish cur.

If turning (or boring for that matter) up to a shoulder, it's not uncommon to stop just shy of it and hand feed the last few thousandths. Just how close depends on your comfort level. You don't want to crash.
Charles,
Just note that anytime you stop the feed you will leave a line on the surface of your work. If you have the room, time and reflexes you can often whip the tool off the job as you disengage the feed. But like others have pointed out, you dont want to crash the job.

I must admit to being a little confused by the thread, and the answers. Is this a mill, or a lathe? If a lathe, what do you mean by "feed lever?" Are you referring to the half-nut engagement lever? If so, I was under the impression that that should ONLY be used when threading. Or, is that only on a South Bend? Do other lathes operate differently?

The lathe is being referred to here. The feed lever engages the carriage to the lead screw for automatic left and right movement. Some lathes known as Manual Lathes don't have this feature. This is not to be confused with the half nut lever. That is for threading. Have I answered your question?

Just a nudge for clarity "feed Lever" "half nut lever" usually not the same but some lathes feed with the half nuts such as the asian 7 x 10 etc, while most are driven separately. Half nuts engaging the lead screw for threading, and feed control lever engages the feed shaft.
End result is the same as to method no matter the lever, Disengage the feed before hitting the shoulder. It is usually a good idea to try it under load, while feeding at depth to avoid a surprise. I once got a hold of a machine that didn't want to turn loose on a hogging cut.
