I don't think tolerance stacks is tolerance analysis. Tolerance stack is one method of performing tolerance analysis. The way it is described on this page, it appears as if tolerance stack is same as tolerance charts. The two references cited are both for tolerance charts.

Tolerance Analysis can be conducted by various methods a) Tolerance Charts (Basically one-dimensional analysis) b) Simulations (Monte Carlo and others) c) Parametric or linerized (1D, 2D) tolerance Analysis d) Academic Research math models for tolerance analysis (Offset zones, Variational Surface, Kinematic, Vector Spaces, Variational Surfaces, Degree of Freedom, TTRS, T-Maps, GapSpace, Clearance Space, etc)

review papers for such methods and tolerance research are:

## Naming the Page

This page and any discussions on Wikipedia about this subject should be titled "Tolerance Analysis." "Tolerance Analysis" is the general term for all activities related to the study of accumulated variation in mechanical parts and assemblies, and may even be expanded into other types of systems, such as electrical systems.

The issue at hand is this:

"Tolerance Stack" is actually a slang term, jargon usage, and a shortened version of "Tolerance Stackup" or "Tolerance Stack-up." Tolerance Analysis includes all types of studies used to predict or comprehend accumulated variation.

"Tolerance Charts" is a slang-jargon term, naming the analytical process after the form used to compile the information used in the analysis. This is inappropriate. Although you may find references to the term "Tolerance Charts" in certain literature, it is not the best term to describe the subject or the activity.

As a comparison, "Stress Analysis" is the term used in industry and academia to describe the analytical methods used to calculate the stresses that may occur in mechanical parts and assemblies. "Tolerance Analysis" is of a parallel structure, and like Stress Analysis, describes the general activity being performed.

I strongly suggest that this article should not be changed to "Tolerance Charts." The title of this article should be "Tolerance Analysis."

Thank you.

This article needs some work. Either the article needs to be renamed to tolerance analysis or a separate article needs to be created at tolerance analysis and the topics split. Wizard191 (talk) 23:14, 27 May 2009 (UTC)
Agreed. As of this posting, there is a Tolerance Analysis article, albeit very short and incomplete. As a start, how do we migrate the information in this article to the Tolerance Analysis article, then create a redirect from this page to the Tolerance Analysis article?

Done. Wizard191 (talk) 21:12, 24 September 2010 (UTC)

## ASME Y14.41

I suggest eliminating references to ASME Y14.41 because it is a document about depicting tolerances that are described in ASME Y14.5. It has nothing at all to do with tolerance analysis.Three d dave (talk) 05:12, 5 May 2015 (UTC)
