Well, I have finally gotten the rigid tapping working, but I'm not totally satisfied with the results. I'm getting a little mauling or damage to the top part of the threads.
I am using combined drill-taps. What I am doing now is drilling the hole through first, then pulling the tap back, and starting the G33.1 tapping operation with the tip of the drill-tap even with the top of the material. This makes the G33.1 return the tap to be completely outside the material while the spindle is in reverse. So, I think the damage to the threads is because I'm giving the drill-tap too much axial freedom in a home-made spring-loaded tap driver. I had one anomaly where the spindle just mashed down onto the tap and smashed it to pieces. At least, that's what I THINK happened, it happened very quickly. It reminded me of the problems I had last year when the spindle sync/home to index pulse function had several problems in it. I ran a bunch of air tests without a repeat, so I wnt back to production and had no further problems. I did manage to tap 208 holes with this setup.
