Expert System for Modular Boring Tool System

Abstract

For a build-up type modular tool system used for boring, a boring bar is constructed by combining basic parts such as a shank (or basic holder), accessories, boring head, tip holder, and cutting edge to match the shape and properties of work. The individual basic parts, however, are of such diverse kinds that they provide a vast number of combinations. For this reason, a considerable length of time is required for selection of an optimum combination of basic parts, and this considerably reduces the intrinsic value of the build-up system requiring less time in fine adjustment of cutting edge and tool wear correction.
This paper discusses an expert system developed for higher accuracy and speed in selection of an optimum combination of basic parts for a modular boring tool system. We have only to specify the shape of work, its material quality, etc. in the conversational mode. The expert system will then select an optimum combination of basic parts, and will output the result of selection, cutting rate, feed rate and other boring conditions in a short time.
