: : What is the real difference between angularity and profile of a surface. Are'nt they interchangable, same thing?
The difference is seen in the following:
1)requires datum reference(s)
2)controls only orientation of axes, line
profile of a surface -
1) may not require datum reference
2) can control co-planarity, location,
orientation (surfaces, not axes), form
So, there is overlap between the two controls, but neither is a superset to the other making eliminating either one difficult.
* Also controls form indirectly by limiting departure of surface - similar to flatness control
