Occasionally I’m asked why the content of the Help function of one of the software applications in the Toolkit is not visible. It just says “Navigation to the webpage was canceled”. Another problem is that on high resolution (high DPI) displays under...

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...

The flexure hinge is a proven design element in precision engineering systems. It is created by drilling or spark erosion of two adjacent holes. The positive characteristics of flexure hinges, free of backlash and friction, are partially offset by the limited angular...
