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... by Jaap Vink | 2 Mar 2023 | Blog, Tolerance Analysis
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... by Jaap Vink | 14 Sep 2022 | Blog, Tolerance Analysis
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... by Jaap Vink | 21 Apr 2020 | Blog, Tolerance Analysis
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... by Jaap Vink | 28 Mar 2015 | Blog, Tolerance Analysis
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... by Jaap Vink | 16 Dec 2013 | Blog, Tolerance Analysis
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... by Jaap Vink | 22 Nov 2013 | Blog, Tolerance Analysis
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... by Jaap Vink | 18 Oct 2013 | Blog, Tolerance Analysis
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...
