What is Tolerance Analysis?
Part 2 of DCS's Back to Basics Series
Tolerance analysis is the name given to a number of processes used to determine the overall variation and effect of variation on products stemming from imperfections in manufactured parts.
As part of the tolerance analysis process, both original sources of the
are determined, as well as a stack-up, that is, the combined variation of all parts in a given assembly. By analyzing the effects of dimensional part and process variation (tolerance analysis), manufacturers can better understand the source of dimensional variability within their design, rooting out potential issues before they become problems, reducing scrap rates, assembly fit issues and meeting customer expectations for dimensional quality.
