“…a hole is needed to accommodate a bolt and may be created by a drilling operation. For this reason, more functional definitions have been used including "a geometric form or entity whose presence or dimensions are relevant to design and manufacturing functions" [5]. Moreover, as pointed out by Gindy [14], "features ... in a geometric model become context specific and highly dependent on the application that the model is used for".…”

Feature-based design (FBD) has the potential to optimize several aspects of the design and manufacturing process. One such aspect that has not been fully investigated is the link between FBD and rapid prototyping (RF). Using features that contain information specifically tailored to the requirements of the RP process, it is possible to optimize this link. This paper describes a methodology designed to achieve this and discusses several examples of its use. The main benefit of using the methodology is the creation of RP models that reflect more precisely the designer's original intent. Future work required to suppon the application of the methodology is outlined.

“…Recently, some efforts toward automated design have been made by researchers such as Dixon and his colleagues [9] who developed expert systems for mechanical design. The term "mechanical design" is most often defined as the creative decision-making process for specifying or creating physical devices to fulfill a stated need [10].…”

Abstract. Although more and more expert system shells have begun to provide communication interlaces to conventional procedural languages, the interlaces are basically shell-and language-dependent. This paper presents a simple, shell-and language-independent data communication technique between a shell and a procedural language via a concept analogous to the handshake data transmission used in microprocessors. A control file is used for the action of handshake. The communication interlace is between two data files in two different language environments. A program written in a LISP-based expert system shell, OPS 5, and one written in a procedural language, FORTRAN, were tested to verify the presented technique.An expert system for cam motion specification, which needs the following three tasks-symbolic representation, numerical computation, and their communication-is described as one of the possible applications of the technique. These three tasks are essential to automated engineering design and analysis.

“…The major consideration in CAD/CAM integration is how to represent the design and decision logic. Representing the design information in terms of its features has been considered effectively by many researchers (Dixon et al 1985, Garth et al 1989, Shah and Bhatnagar 1989. The feature extraction and the design with features are the two most popular kinds of approaches to obtain the part's feature information (Hummel and Brown 1989).…”
