I have been looking at adding tapered threading to G76. My understanding is that coordinated motion is synchronized in X, Y, and Z. So for instance, a tapered thread would have X and Z motion and would start and end at the same time by using an appropriate distance per encoder count rate for each axis. For a tapered thread, the pitch would be along both Z and X, as opposed to the thread axis on Z. This seems to be okay, since a little bit of math can correct this issue. My problem comes about in considering the compound slide and regression features, and in trying to save the lead in and out taper option. The paths get quite complex and it seems since motion is synchronized by path distance, each path needs to be the same distance, and X motion without Z motion, plunging, counts. An X only plunge would offset a following Z motion and if the plunge needs to be deeper each pass the helix gets an angular shift.
Am I correct in thinking coordinated motion uses X, Y, and Z together.
