CHECKING PARTS ON A FIXTURE


Recommended Posts

I am currently having a major brain lapse and could use some help. I have a fixture that i designed, part sits on three tooling balls and has stops on it. Anyways, i have scanned the fixture b/c that is what is used for my alignment and I do not want to scan it ever again. The fixture is on a plate so it will not move. I want the operators to be able to just come in and run the part and not have to worry about scanning the fixture and then putting the part on. For some reason today I cannot get the dang program to run without rescanning the fixture. I've done this before and i cannot for the life of me figure out what I am missing today

If the fixture alignment is the base alignment, you'll have to run it each time. Create a start alignment on the fixture and a base alignment on the part. Then you initially run from start alignment the first time, then and after that you run from the base alignment.
Also put a 3x loop in the base alignment, in case the part doesn't repeat landing in the exact same spot each time (within reason), and it will probably be off a little each time due to part variability. unless you've got an extraordinarily robust fixture.
