Abstract

An expert system of the grinding process has been developed, which makes it possible to predict and optimize the process of defect-free processing of both existing and newly created superhard materials. The expert system consists of two interconnected modules - theoretical and experimental. The theoretical module of the expert system allows, at a given level of significance, to determine the values of the output indicators and the kinetics of their change in the process of adaptability, depending on the physical and mechanical properties of the interacting materials and processing conditions. The experimental module of the expert system allows you to coordinate and correct the results of theoretical calculations when determining the optimal grinding and operating conditions for processing various grades of superhard materials. When optimizing the sharpening process of a blade tool, processing efficiency, consumption of diamond wheels, cost price and various quality indicators of its cutting elements can be selected as a criterion. The use of the expert system significantly reduces the amount of expensive and laborious researches in determining the optimal processing conditions for various grades of superhard materials (SHM), including newly created ones.
