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
As long as datum -B- is measured as a 3d feature, you should be able to level to it as +Z and set both the X and Y origins to it. Since the measured feature will be coaxial to -B-, in theory, you do not need a rotational lock (X = 0; Y = 0). You will, however need a rotation for reference if you expect to be able to adjust based on the results.
