Abstract
Concurrent engineering is a desirable goal for manufacturing-based corporations as it will ultimately reduce costs and time to production, and improve quality and productivity, thereby increasing profits. Our vision of concurrent engineering is a set of critics observing and providing criticisms on the design and recommending design changes. Such criticism is provided on a single part by one critic at a time. The critics share databases, and they may be either human or computer experts in the specific product life cycle issues. Our bottom-up approach to concurrent engineering involves the creation of a manufacturability critic for the current phase, then the creation of other critics, and finally the creation of the concurrent engineering control system in the future.
The manufacturability knowledge is obtained from design rules in handbooks or from the minds of experts. The rules are based on geometric shapes of objects known as features. All features required for such analysis are not available from most CAD systems, therefore, they need to be recognized. We use a heuristics-based approach to recognize features and use them as input to the manufacturability critic.
