Ever since the plus/minus limits on dimensions first started to appear on engineering
drawings in the early 1900s, tolerances have been one of the most important issues for …

Three dimensional (3D) tolerance analysis is an innovative method which represents and
transfers tolerance in 3D space. The advantage of 3D method is taking both dimensional …

Engineering design research shows a rather fragmented, if not a chaotic, picture. But does it
have a hidden order? Can we explore it, or should we impose a reasoning model? This …

The aim behind applying functional tolerancing to a mechanism is to widen the tolerances
used in parts manufacturing according to the effective functional properties of the product …

The paper surveys the current status of the models for representing, manipulating and
analyzing dimensioning and tolerancing data behind the major computer-aided tolerancing …

In this paper, an ontology-supported case-based reasoning approach for computer-aided
tolerance specification is proposed. This approach firstly considers the past tolerance …

This paper presents a model of prismatic parts (PPs) inspection planning on CMMs, in terms
of an intelligent concept of inspection planning. The developed model is composed of …

The paper describes a method for the generation of tolerance specifications from product
data. The problem is nontrivial due to the increasing adoption of geometric dimensioning …

In most cases, designers have to manually specify both assembly tolerance types and
values when they design a mechanical product. Different designers will possibly specify …

Over the past 70 years, product design has undergone many important changes due to the
impact of contemporary digital technologies (ie digital design). To support digital design and …
