My employer prepares test specimens of various exotic materials for tensile testing. These samples are 3" long cylindrical pieces, with 1/2-13 threads on each end for about 3/4 inch. These need to be chased and cleaned up for the holders of the testing machines, and they can't be just hit with a thread file - too hard.
So, we use a threading canned cycle in a CNC lathe, eyeball the first few strokes, stop and adjust in Z until it runs correctly. Then 27 strokes later, we check if it came out ok. If the threading tool was chipped partway thru, we run it again until a guage goes on smoothly.
Today I was asked to speed up. I am new, and somewhat flabbergasted at the request, since I work my butt off and try very hard to do things the way I am shown. I would love to reduce the number of strokes used, since we are not actually cutting the entire material, but simply cleaning up the existing threads.
Any thoughts, oh great and wise ones?
