Feature Based Design

Abstract Virtual reality systems have been developed over the last few years to provide real time, immersive, three dimensional rendering. There have been efforts to utilize virtual reality and other similar approaches for design (Jones, 1996); however, limited information has been placed in the open literature describing the development of systems used specifically for the design of complex products, like naval vessels. As added motivation, features have been widely accepted as a useful paradigm for design purposes, but experience with feature based design in a virtual reality environment has also been limited. With these issues in mind, this paper was written to describe an ongoing research project that focuses on the demonstration of feature based design in a virtual reality environment for submarine design. To support this development, progress to date using the GROTTO, a CAVE like system, at the Naval Research Laboratory is reported. A “spin-off” of the research to web based collaboration is reported, an outline of projected system architecture is provided, and conclusions are drawn regarding the development of the virtual system.

Abstract A feature-based design environment for machined parts exploiting the capabilities of mill-turn machining centers is described. Part models for prismatic, turned and mill-turn parts, as well as hybrid parts such as turned parts with prismatic features, are created with parametrically defined features. Two-dimensional (2-D) profile features are used for creating surfaces of revolution for turned parts. Mill-turn features can be added to cylindrical base features, and traditional prismatic features, such as slots and holes, can be used with prismatic or cylindrical parts. Features are hierarchically positioned and oriented in a unified scheme that includes position and form tolerances. The vector-based tolerance representation facilitates interactive three-dimensional (3-D) design and provides information needed by downstream applications, such as automatic process planning and inspection.

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.

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).
