Automatic Generation of NC Programs for Turned Components from Cad Product Models

CADEXCAP: Integration of 2D CAD models of turned components with CAPP

“…To allow for the variation in practice between companies, the system provides a knowledge engineering toolkit, allowing the end-user to tailor a standard set of manufacturing knowledge to suit particular requirements [23]. This paper describes software called CADEXCAP, which has been developed to integrate EXCAP with CAD systems via IGES.…”

Product representation for an expert process planning system for rotational components

“…It has been developed at UMIST, and is designed to automate process planning in different companies. To allow for the variation in practice between companies, the system provides a knowledge engineering tool-kit, allowing the end user to tailor a standard set of manufacturing knowledge to suit particular requirements [15].…”

Feature technology: an overview

“…Despite this, some systems still extract feature information from 2D models (Wang, 1987, Wang and Wysk, 1987, Mortensen and Belnap, 1989, Lui et al, 1991 or apply 2D feature representations for rotational parts (Joseph et al, 1990, Varvarkis, 1991.…”

“…Each template usually corresponds to a feature (but could, for efficiency reasons, represent a composition of several features). The rule based approach is suitable for knowledge based expert process planning systems , Mortensen and Belnap, 1989, Wang and Wysk, 1988and Joseph et al, 1990.…”
