    NEWBIE to Citizen - G32 thread whirling on Citizen L520???

    I have just been thrown into the Citizen world after using Star machines for a while. I have never had to whirl a multiple angled thread on the Star and now I have to do just that on our new to us Citizen L520. The whirling head rotates about Y0 to set the helix angle, so if you whirl a taper it has to move in Y and Z doesn't it? Can you call a G32 thread cycle and have it move YZ?

    The coordinates that I have to whirl along are:

    (start of thread) X-.0088Z-.05
    (1st end point)X.0312Z.063
    (2nd end point)X.059Z.197
    (final end point) X.059Z.283

    Did I mention that these are TINY?
