    Hardinge Elite 27-Does opening main collet cause program reset?

    Our bar feeder is down currently, so we're running a bar job where we need to pause the program, open the collet, and manually advance the stock up to a stop in one of the tool positions in the turret. The setup guy/operator is telling us that the program resets to the beginning when he opens the collet. Does this sound right? I rarely program lathes, and I am not at all familiar with this particular lathe. I would like to try this unless someone can tell me it won't work:

    M21
    M00 (MANUALLY ADVANCE STOCK TO STOP IN TURRET)
    [CYCLE START]
    M22
    (tool change, resume program)

    Thanks in advance for any help.

    Try putting it in Jog mode before opening collet. That is what I usually do, so I don't have to turn off the barfeeder.
