Got a part with a lager Id bore that is datum b. Going into the part morr is a smaller bore with a position of .003 to b.
So my fcf used the drf to control it. Well the report does not show x and z as zeros. Engineering says datum b is zero so the report has to show everything as zero. So I did an alignment using just datum b( center line of the cylinder) the report show zeros but bad position and does not repeat. What am I missing
I agree. Exactly what I tell them. But you and i are wrong.
No need they shipped the parts out. They got them Good with a height gage pins an d calipers.
I was given about 30 minutes to write this program. rhey wanted measured and had a program run time limit of not more then 10 minutes. The part has to have a set up thay a machinist can run this part as they pull it off the machine. If a machine is down longer then we have to find a faster way to measure. In this case they did some pin checks a few caliper checks and a couple height and called it good.

The fact that they limit the runtime of a CMM program boggles my mind. I'm all for making sure code is streamlined, but not at the expense of the efficacy of the checks!
