I don't think what your proposing will work correctly, although I am really not to sure where you are going with this thought?
This is all new to me Al , I understand the process, but I do not understand what application will work better,and thank you for the hyperlink but I don't know what application will work, for instance- i don't know what a Z servo will do- ?what I do know is that I need one to move the carriage down the bed, and the other to turn the Headstock spindle, what servos or axis is all new to me.

You have to decide whether you want to go mechanical or electronic, the link showed examples of almost exactly what you want to do, electronically i.e. Synchronize the carriage movement to the spindle rotation?
I am assuming that what you want to do is very little difference from threading in a CNC application.
As I mentioned earlier, an encoder on the spindle would be used to electronically gear the carriage (Z axis), if neccessary with live tooling.
This would exactly replicate the mechanical method but implement it electronically.
Even with using the Galil and programing with native commands is not a trivial undertaking, as will be the case with any other electronic method.

BTW, in CNC terms, the X axis is the cross slide, (radial to the chuck) the Z axis is the carriage (axial to the chuck) and if the spindle is used as a rotating axis or is referenced to the Z for example, it is the C axis (rotates around the Z)
