In current tolerancing practice, designers have to manually specify tolerances: either on a
drawing or in a CAD system. Different designers will possibly arrive at different tolerance …

When designing a mechanical product, how to determine its assembly tolerance
specifications (ATS) and tolerance zone types (TZT) is a complex design problem, in which …

A computer aided tolerancing tool is presented that assists the designer in functional
tolerance specification. The theoretical concepts for subsequent tolerance analysis are also …

In this paper, interactive “constraint based feature definition” is used to drive both feature
based design and feature recognition. At present, hardly any feature based CAD or CAPP …

This paper describes an attempt to capture and to represent product information, which is
used for generating product definition, but is not explicitly represented in product description …

The paper argues the point that thanks to a recent shift of emphasis from logic based to
autonomous, rational and interactive models of intelligent behaviour, artificial intelligence …

Sharing design knowledge within a company is critical to retain market competitiveness,
especially when the company develops a family of products. The goal of this study is to …

This paper discusses three different issues in feature classification. It proposes a complete
taxonomy to cater for prismatic and rotational features which can be positive or negative. It …

This paper describes the development of computational support tools for practically
successful engineering techniques. The paper reviews the requirements for manual Quality …

Current Computer Aided Design (CAD) systems can capture some of the design intent by
creating associations between objects. This increases the productivity during product …
