Study on the Testing Method of Cemented Carbide Tool : On the critical Value of Flank Wear

Abstract

Boston and others have introduced the mean value of flank wear 0.03" as a reasonable designation for tool life. But our experiments show that the critical value of flank wear is not always constant and therefor it should be controlled by the kind of carbide tool, material cut, cutting condition and tool design. Arranging our experimental data, we proposed a summary table of the critical value of flank wear.
