Dual turret (or spindle) machines do seem to come in an incredible variety of languages. I remember one particularly awkward machine that used z_[1]x through z_[5]x to define which spindle you were moving, followed by a g-code to tell it to actually move the Z-axis. Normal Xn Yn Zn moves would move all 5 spindles at the same time.
I was referring to how linuxcnc currently handles those words - but this thread seems to have rekindled some discussion about how to handle multi-tool machines in linuxcnc. If I can retain the UW syntax I will, but the methods I have tried so far won't allow it. The remapping method suggested by Michael Haberler may or may not allow the use of these words, but would require a different method to define the profile. I never really understood why UW in G71 were that essential, IK seems to do the same job with the added bonus of a smooth pre-finish cut. I suppose it depends a lot on the part.

When reading the U, W words they are reserved for axis movements only. >2. Some lathes are XZ/UW - so the UW words are required for the second tool. As far as I know Fanuc don't use UW for axis in lathes or turning centres, they use XYZABC and I believe they also made two co-coordinated and interlinked controls with two sets of XZ - but I've never come across one. I think they used X_ Y_ Z_ for the second toolpost on that control. I've also seen it without the UW words at all, but can't remember what control. They do seem a bit superfluous and are optional on some. No great shakes to program the actual size the roughing cycle is going to cut, rather than the finished size plus an allowance.
