Geometry assurance and robust design

Question 1

What is geometry assurance?

Answer 1

Geometry Assurance is the set of activities that aims to minimize the effect of geometrical variation in the final product.
Geometry assurance is to a great extent supported by simulation and digital tools.

Question 2

What are the main “parameters” of geometry assurance

Answer 2

1. Locating schemes (controls robustness)
   - Where are the contacts?
   (Relates to the assembly process)
2. Tolerances (controls variation )
   -How much variation?
   (Relates to part manufacturing)
