AbstractA knowledge-based Prolog program is presented that interprets the annotation information of a CAD drawing in terms of geometry primitives derived from the wireframe model used to create the...
View ArticleImplementation of a “backwards planning” technique in the automation of...
AbstractIt is essential to automate the process-planning function to achieve true integration of CAD and NC machining for computer-integrated manufacturing. Several planning techniques have been used...
View ArticleElicitation of process-planning knowledge in a manufacturing environment
AbstractSeveral research organisations are currently employing expert-system techniques for automating the process-planning function. Gathering the knowledge from the experts (in this case the process...
