Need some help

I am new to using PC-DMIS and trying to write a program. I have aligned the part and taken my measurements. What do I need to do so that when I move the part and put a different(butsame) part on my table it will be able to automatically run the program? Will I need to do a manual align everytime the part is moved? Thanks in advance for the help.

YEP, you have to do the manual alignment every time the part is put in a new location.

If you DON'T want to do the manual, you have to come up with a correct, suitable fixturing system.

Ok, So if I write a program for an operator to use I should puyt instructions in the program on how to align? I thought there was some way you could sit a part on the table, open a program for that part, pc-dmis would say " measure cir1, cir2, pln1 and it could recall the original alignment and move it to where the part is currently sitting? Thanks for your help!

That's pretty much the alignment you are talking about with the "measure cir1, cir2, pln1",

Ok. So there is no way that you can make an alignment, move the part and recall that alignment and pcdmis will "move" the alignment after you take a few points?

I would think if you gave the program the measurements of Datums A, B and C and aligned, then you could move the part, measure Datum A and it would know hwere B and C where located. Then it would measure B and C and align it automatically?

look at the 'datums'.. "A" would be a plane (3 DOF) and wouldn't lock down "right to left" OR "front to rear". 3 DOF left to lock down.

You could do this with a readpoint. Look at this thread.
Also search readpoint in the forum.
Basically, you place the probe near a corner or a hole, align to that and run from there.
The part has to be fairly square to the axis', but the location can vary.

Some training or even some trial and error would help you out tremendously. Alignments have been beat to death on this board, a quick search would give you several good ideas. If nothing else go ask a set up machinist how they do it, its the same thing.
