Hello,
I'm trying to understand something and hoping someone could help.
I have parts that call out just basic surface profiles 1.0/A/B/C or +/-0.5mm.
I normally create individual vector points on the surface, measure the points, and report out the "T" values at +/-0.5mm.
For this new part we have, reporting like this shows very good, consistent parts that exactly match what I'm seeing from checking the parts on the fixture gage.
However, we have a new program manager that says I have to report X,Y,Z & T for every point.
Of course, when I do this, the two-dimensional X,Y,Z's are causing this manager to freak out saying that the die is not producing consistent parts.
I've tried explaining to him that X,Y,Z are two-dimensional and the only surface measurement that matters is the one that is parallel to the surface's normal vector, but he seems to think I don't know what I'm talking about.
Are you guys in agreement with me or do I not know what I'm talking about???
I've been in metrology for more than 20 years so, I hope I know what I'm talking about here.
Please, someone give me your thoughts and maybe suggestions on how to explain this to someone who's not very familiar with metrology.
