Optimization of fits and clearances between parts in an assembly.
Our Expertise
No physical parameter is perfect. Engineers must deal with the fact that a dimension, resistor-value, chemical concentration, or spring rate is known to within some +/- tolerance. Everything is described as a statistical distribution about an expected value.
At the beginning of a project, the skilled design engineer is incorporating approaches and architectures that reduce the ways in which these tolerances can “stack up” and cause problems.
Towards the end of a project, engineers perform statistical tolerance analyses to determine the impact those stack-ups.
