Haas center of rotation parameters

[So not a Guru]

We want to program our UMC-750s to the center of rotation & we want to be able to run programs in either of the 2 machines we have on the floor. I generally import a manual entry that assigns the G54 values with the known parameters of the machine (#5221=xx, #5222=yy, #5223=zz), but in this case we have two machines with, of course, different XY & Z values.

So, I figured I'd just pass the machines values thru: #5221=#xxx. The trouble is that the rep from Haas has given me 2 different parameters for the center of rotation (X=#255 & X=#10121), but neither is correct.

So, I thought I'd ask here if anyone knows what the center of rotation parameters are for a Haas UMC-750.

I am pretty sure that on Haas and Fanuc controls the standard is still #5221=X, #5222=Y, and #5223=Z. Not the others the rep gave you? You could also preload using a G10 lIne.

Why not just have an offset that's COR for that machine and leave it alone?  Shouldn't have to update it to the same number every time you run a program.  I use G59 as COR for my trunnion and only change it if the trunnion moves.

Have you explored the DWO and TCP options that are on the UMC-750 Control? The Dynamic Work Offset in particular should take care of your issues, and allow you to simply place your part on the machine, measure the offset amount, and have the control compensate for any misalignment.

 you can find  X , Y ,B ,C , on your own with an indicator. so every machine is a little different because of machining the casting  so  if you really want  Z , you will have to have haas come out there with the key and unlock the trunnion and probe the table 90 degrees right and with the haas key 90 degrees left then divide by 2 that will give you the Z value you are looking for.

and there you have it.
