A previous article described the entire step-by-step plan for building a tolerance chain. It was described using a relatively simple example. In practice, however, designs can be much more complex. And then the tolerance analysis of such a design is much more...

The article ‘Step Plan Tolerance Analysis’, briefly summarizes the steps to achieving a good tolerance analysis. The following articles discuss the method of adding tolerances. Much attention has been paid to the Statistics of Dimensional Variations of...

Previous articles have discussed the use of statistics in tolerance analysis: how statistical summation works, how to account for the influence of different distributions, and how to combine worst-case with statistical contributions. The resulting picture is that the...

In previous articles about tolerance analysis, I discussed the step-by-step plan and how to add up tolerances. The sum of tolerances can be a worst-case sum or a statistical sum. In ‘The Distribution of Tolerances’ I also discussed the types of...

A previous article discussed statistical tolerance stack-up analysis. It is usually more profitable to perform a statistical tolerance stack-up analysis instead of a worst-case analysis. A worst-case analysis often leads to low tolerance specifications and therefore...

In the Worst-case Tolerance Stack-up Analysis article, you will read about worst-case or linear stack-up analysis. Such an analysis assumes that all dimensions in the tolerance chain have worst-case deviations from their nominal values. A statistical tolerance...

Suppose you have gone through your tolerance analysis step plan and created a tolerance chain. Now all you have to do is add up all the tolerances. This seems simple enough, but there are a few issues to consider: What do you do with asymmetric tolerances? Do you...

Tolerances become important as soon as you design an assembly of parts. Of course, each dimension must be given a tolerance. But in an assembly, tolerances become important because all the parts must fit together. In this article, I will implicitly assume that we are...
