Abstract

The influence of a great number of parameters on tool wear in hot die forging of steel is very complex, and thus the relations between these parameters and the wear are highly non-linear and spatially very disordered. Even small variations (though within allowed limits) of the chemical composition of the tool material, in heat treatment conditions, etc. can cause considerable scattering of data on tool wear resistance. Therefore wear can be hardly described mathematically either by phenomenological models or by common regression equations. A better solution in predicting tool wear (the arbor radius) is given by applying a hybrid model, that
