• Geometric concepts are now much easier to read and understand. • Revisions emphasize use of basic dimensions and geometric tolerancing as the preferred way of controlling the form, orientation, and ...

Abstract: We examine the representation of geometric tolerances in solid-geometric models from the perspective of two classes of functional requirements. The first class deals with positioning of ...

Geometric Dimensioning and Tolerancing (GD&T) has been around since the 1940s, yet it is unappreciated as a way of finding bad designs before parts get made. • Tolerances are a vital part of ...

How does a design go from the computer screen to something you hold in your hand? Not being able to fully answer this question is a huge risk in manufacturing because . One of the important tools ...

This 5-day course focuses on tolerance stackup and tolerance analysis in mechanical designs, emphasizing the impact of dimensional variations on product form, fit, functionality, and manufacturability ...

Abstract: In a companion paper, we examined the representation of geometric tolerances in solid models from the perspective of certain functional requirements. We showed that assembly and material ...

One of the challenges facing precision manufacturers and their medical device manufacturing partners is the increasing feature complexity of tight-tolerance parts. These complex geometries can result ...
