I think I have a grasp of how this thing works now. My only question left is, if the "teeth" are in rings, and there are multiple rings (and assuming the thread mill is spinning at that same time as the x and y axes are moving), how does the tool keep from munging the threads that are already cut if there is no "screw" ramp to them? From the looks of the thread mill in the picture, the thread mill's "rings" all seem to be parallel with each other, and have no screw ramp.
