A Tolerance Stack-Up Analysis is an analysis used by designers and
engineers to determine if an assembly of parts will fit together and function
properly. The analysis is based on the dimensioning scheme of the individual
parts and how they are assembled.
Here’s an easy way of looking at it: Assemblies are made up of parts.
Every part contains dimensions to define the part. All dimensions have
tolerances. Since it’s actually impossible to manufacture a part perfectly to a
given size, designers provide a tolerance, or a range of error that is
acceptable for a particular feature in a part. What engineers worry about is
what happens to the fit and function of their assembly when all those parts, with
all those tolerances, get assembled together. Can they be sure that their
assembly will fit together and function properly. This is why they perform a
tolerance stack-up analysis.
What is SolidWorks TolAnalyst?
---TolAnalyst is a tolerance analysis application provided since 2007 in
SolidWorks 2008 Office Premium that determines the effects that dimensions and
tolerances have on parts and assemblies. The TolAnalyst tools let you perform
maximum and minimum tolerance stack-up analysis on parts and assemblies.
See you next week with some other features of SolidWorks.
