Question 1

What are three important advantages of profile tolerances in comparison to coordinate tolerances?

Accepted Answer

Three important advantages of profile tolerances are:
1. Profile tolerances provide a clear definition of the tolerance zone
2. Profile tolerancing communicates how to hold the part for repeatable measurements
3. Profile tolerancing eliminates tolerance accumulation

Question 2
