Abstract

This paper describes an expert system for selecting the optimium cutting conditions, which enables us to arrive at the conditions in a similar way to the practice in actual machine-shops. The way of thinking of expert tool engineers for obtaining the optimum cutting conditions was first examined through a questionary investigation. The system was then constructed so as to possess the same functions as those in their way of thinking. The most important functions of the system are the prediction and the resolution of machining troubles such as chatter vibration, excessive tool wear and rough surface finish. Two different approaches are taken depending upon the kind of the troubles, which are retrieving data method with aid of the evaluating functions and analytical method through the algorithm of the metal cutting theories. As an example of the latter method, a sub-system for evaluating tool wear is developed together with a filling up method of its data base. This system is also proved to work well by experiments.
