FEMEX

Establishing a Working Group for Feature Modeling Experts

Dr. Jivka Ovtcharova

1. Motivation

Current research and development in the area of CAD/CAM is concentrated on the integration of advanced product modeling tools and methods providing users with facilities to capture engineering semantics of product parts as well as geometry in the part models. Since different types of information have to be represented and manipulated in a uniform and expressive manner, the product life cycle as a whole becomes more important. This leads to the definition of comprehensive models, product models based on integrated data.

Recently, features have been identified in the engineering community as meaningful semantic entities enabling humans to reason about products and processes. From the designer's point of view, features are functional primitives, which serve as the basis for product representations, improving the quality of the design and the link of life cycle activities, such as process planning and manufacturing. Over the past years, feature-based CAD systems have reached a significant impact in industry, having the potential to improve and speed up the design process, to reduce the cost and to shorten the time-to-market.

Currently, three different types of organizations are working in the area of feature modeling: universities and research institutes, CAD/CAM suppliers and industrial users (Figure 1). The universities and research institutes are providing theoretical knowledge and experience in application-oriented research and prototype development. System developers are specialized on the commercial software development for CAD/CAM, and the industrial users have a broad technical and technological know-how in different application areas.

In such a situation where each type of organization has its specific advantages it is of crucial importance to bring these three groups together. The aim of FEMEX is to provide such a forum for discussion and cooperation.
