The Milling Assistant

Burd, W.C.

A knowledge based computer program that assists programmers of Numerically Controlled (NC) machine tools is described. The program uses part features identified by the NC programmer at a CAD/CAM graphics display and a set of manufacturing rules to select machining parameters and produce NC part programs. An expert system determines the correct NC sequence and the machining parameters. Both milled and point-to-point features are programmed by the Milling Assistant. Examples are included to illustrate the problem domain. Extensions to the Milling Assistant are described. 11 refs.
