Abstract

This paper describes details of a prediction system of tool wear. The system is based on the wear characteristic equation and the three-dimensional cutting model relating to formation of a lateral curl of chip which have been proposed in the previous papers. The prediction method yields not only tool rake and flank wears but also distributions of temperature and stresses on the worn surfaces under arbitrary tool geometry and cutting conditions, provided that basic information, such as orthogonal cutting data, thermal properties, constants in the wear charac-teristic equation is in hand. The tool wear configuration, wear progress curves, tool face temperature, etc. thus predicted are in reasonable agreement with the experimental ones. The reason that the wear at the corner part decreases when turning 18% Mn steel with tools having a relatively large corner radius is due to the temperature drop which is mainly caused by the decrease in the undeformed chip thickness at the corner part with increasing corner radius.
