Abstract

This article attempts to show how the theory of fuzzy sets may be used in explaining non-monotonic behaviour of the tool life function. Results obtained in orthogonal turning of Stellite cobalt alloys served as a basis for presenting rules underlying the so called areas of undetermined chip formation and for determining local extremes of the function. Fuzzy set theory is presented to the extent that it is capable of explaining the observed bifurcation between two branches of the function.
