Abstract This paper presents a knowledge-base approach that assists a designer to evaluate possible process plans and associated costs based on tolerancing specifications of the designed part. It is an effort to take dimensional tolerances into computer-aided process planning (CAPP) for cylindrical parts through the usage of databases and knowledge bases. Geometric features with tolerancing specifications in a CAD system are first used to determine possible machining operations that can achieve the specified tolerances based on data from the machining feature database, the process precision grade database, and the precision grade database. Process plans are then generated based on rules and knowledge from process sequence knowledge base and the machining feature database. Possible process plans are further organized as a graph. Optimal process plan with least cost is then selected by searching through the graph. This is achieved based on machine set-up and operation costs that are derived from the machine tool resource database, the process parameter database, and the machine set-up and operation cost database. A CAPP software prototype supporting tolerance design on the AutoCAD platform is also demonstrated with examples to illustrate this approach.

Whilst concurring with the new streams of literature in geography that highlight the importance of face-to-face and ‘buzz’ in the globalizing learning economy, we argue that this literature is misleading on three interrelated counts. Firstly, it conflates face-to-face and buzz; secondly, it fails to distinguish between the importance of face-to-face and buzz for industries drawing on different knowledge bases; and, thirdly, these conceptual inadequacies lead to an exaggeration of the importance of cities as sites for creativity and innovation, and hence regional competitiveness. By applying an industrial knowledge base approach, we seek to reconstruct an alternative framework that allows for a systematic differentiation between the importance of face-to-face and buzz for different industries. This provides a framework for developing a more nuanced understanding of the spatial implications of face-to-face communication and buzz for learning and innovation.
