Abstract The increasing application of CAE has lead to the evolution of Concurrent Engineering — a philosophy that prescribes simultaneous consideration of the life-cycle design issues of a product. The Concurrent Engineering (CE) systems that have been developed so far have relied on knowledge bases and qualitative evaluations of a part’s manufacturability for feedback to the design engineer. This paper describes a method for developing quantitative indicators of manufacturability. Feature-based design and estimation of machining parameters are used for ascertaining a part’s manufacturing requirements. These requirements are then combined into indices which lead the designer to features that must be redesigned for improved manufacturability. This method is illustrated on a system for rotational machined parts: the Manufacturability Evaluation and Improvement System (MEIS).

Feature Based Design

The progress with which composite materials are being used in industry has been staggering. The methods, processes and procedures of developing and manufacturing composite materials have always been the center stage for the composite materials research and applications. While feature technologies, in particular feature-based design, have been widely practiced by many in the areas of designing and manufacturing conventional materials, one has not yet seen it help to reap the benefits for composite materials manufacturing. This paper proposed a feature-based approach for representing composite components. Two types of features have been defined, structural and geometrical. Based on the suggested approach toward representing features on a composite component, a concurrent engineering kernel is being developed, in which design and manufacturing of composite manufacturing come together seamlessly to enable a complete product development environment for composite material design and manufacturing.

Feature Based Design

Abstract Many manufacturing companies have been striving to reduce setup times in order to produce smaller lot sizes and to obtain quicker responses to frequently changing market demands. This paper focuses on the reduction of setup time by design improvements of products. Based on the basic principles of setups and concepts from concurrent engineering, rules for design of products at the feature level are presented. Examples and computational results illustrate that the inter-lot setups and in-lot setups can be reduced by the feature-based design rules. The proposed approach for setup reduction appears to be more cost effective than optimizing the processes and operations where the product designs have been fixed. This research intends to bridge the gap between engineering design and manufacturing.

Feature Based Design

Abstract Features are meaningful abstractions of geometry that engineers use to reason about components, products, and processes. For design activity, features are design primitives, serve as the basis for product representations, and can incorporate information relevant to life-cycle activities such as manufacturing. Research on feature-based design has matured to the point that results are being incorporated into commercial CAD systems. The intent here is to classify feature-based design literature to provide a solid historical basis for present research and to identify promising research directions that will affect computer-based design tools within the next few years. Applications of feature-based design and technologies of feature representations are reviewed. Open research issues are identified and put in the context of past and current work. Four hypotheses are proposed as challenges for future research: two on the existence of fundamental sub-feature elements and relationships for features, one that presents a new definition of design features, and one that argues for the successful development of concurrent engineering languages. Evidence for these hypotheses is provided from recent research results and from speculation about the future of feature-based design.
