Just curious, how many have started and/or completed the machining of the Titan 200M. My students have designed it, they had to scale it down, since all we had was 2 x 2" square stock, so they sized it down to 1.960" square. They have completed the 1st op running on our UMC-500. We are looking at our options for probing in the 2nd op… I had suggested we add a x axis stop on our vise and then probe a 123 block to establish the center origin of our 1.960 square. One of my students asked if we centered the part in our 5th axis vise, rotated the trunnion 90 degree and probe the 1.960 across the two flats, then rotate the vise 90 degrees and probe in the other two flats if that would be possible? The logic seemed plausible, I have not tried in in practice yet. How ddi you guys probe in the part to do the 2nd op?
Have part at G54X0Y0Z0 A0 C0 - use that macro that probes on center Not tilted
Most people program Z axis around center of A axis. I think with DWO/TCPC you can shift that Z ( or any axis) if the location is not exactly
Use the Titan pin stop method for a quick locator in X Direction
Pin Stop
With rotations you need to start from what ever view would be A0 C0 or B0 and the orientation codes will be associated to that initial G54 offset
I use 123 blocks all the time its saver and less math that lead to mistakes. your machine has DWO so you good to go. Some times I probe the top of the 123 block too and drop my z 1." in work offsets. Also ill make a work offset your not using like g55 if your parts g54 to match what I probe. so i can compare my changes to g54 to my g55 which i do not change.
Ended up doing something similar, we did not find a way to make the probe retract about 7 inches in Z to use the center slot macro. So we turned the part sideways in our centering vise and added a stop like Titan showed in his video “machining the 200M”. We then used single surface on the stop side and offset half the thickness.
