Representation problems in feature-based approaches to design and process planning

Abstract: A major difficulty in the development of advanced and integrated CAD and CAPP systems lies in the difficulty of representing components. Here some of the problems that are often encountered arc discussed and a composite component is used to demonstrate them. Possible approaches for solving some problems are proposed. The conclusion is reached that neither simple feature oriented design nor feature recognition methods alone will fulfil the requirements of advanced systems. Satisfactory modelling of the interact… Show more

“…There are two main problems that need to be resolved in the feature recognition process. First, feature interactions must be satisfactorily modelled if true automated process planning is to be achieved (Mill et al, 1993;Young and Bell, 1993).…”

“…It is considered to be a significant challenge as, while the number of features may be finite, the features resulting from their interactions are infinite [5,7,12]. A consequence is that 'no general approach to recognize all interactions is yet known' [2,7].…”

“…Hence, several of the interaction cases formally identified here are considered by some feature-based systems [3,5] as invalid situations that should be reasoned with and preferably eliminated. For instance, a feature that is disconnected from the stock material through a volumetric interaction is most probably an error, regardless of its nature.…”

“…Besides, "intended interferences" are common practice in engineering and can be found for example in tolerances, assembly relationships or when assigning distribution patterns of features ( [9], see Figure 1). Furthermore, feature interactions are the cause of some of the most serious problems in the development of generative computer-aided process planning (CAPP) systems, and "are important for determining process sequences and, sometimes the manufacturing processes themselves" [5]. This paper presents a thorough analysis of feature interaction for prismatic parts in the DbF domain that goes beyond already well explored parentchild relationships and geometric 'interference cases'.…”
