## Using the MEboost Tolerance Calculator

The MEboost tolerance calculator allows you to see the potential rejection rate given a probability distribution for a dimension.  This allows you to estimate rejection rate while balancing the necessary tolerance for functionality. A tolerance range is specified by a range of sigmas (standard deviation) around the nominal dimension, or you can directly specify the …

MEboost allows for easy analysis of a tolerance stack.  In this article we’ll show how to perform worst case, root sum squared (RSS), and Monte Carlo tolerance analysis in Excel using MEboost.  If you want more background information on the three methods, check out the tolerance analysis article. The MEboost tolerance analysis tools are capable …

## Tolerance Analysis Methods

Tolerance analysis is an important part of mechanical design.  It has an impact on cost, performance, and quality which requires a requisite amount of study to ensure tolerances result in a successful design that can be effectively manufactured.  In this article we will look at tolerance analysis methods, and their pros and cons.  We will …

## Monte Carlo Tolerance Analysis

Monte Carlo simulation can be used for tolerance analysis (Monte Carlo tolerance analysis) to determine the rejection rate of assemblies.  In this application we will look at an example assembly where parts A and B must fit inside part C with a clearance fit.  For performance reasons we want to minimize the total clearance so …
