A new, physically defined function to describe the wear of cutting tools

Abstract For the crater wear of cutting tools a general model may be established from which—on the basis of diffusion laws—it is possible to derive a physically interpreted wear function. While the wear function is not meant to replace Taylor's curve in practical technological calculations as the conventional T − v function is easy to handle and generally in good agreement with the experimental results, it can be used for examining machinability and cutting quality, and the knowledge gained concerning the mechanism of tool wear—resulting from the physical definition of values and A and B —may be useful in controlling wear parameters. Since this function and the empirical Taylor formula are related in a way which can be described mathematically the wear processes of a cutting tool may be evaluated using the constants of the Taylor formula.
