This paper presents preliminary results of an experimental campaign aimed at mapping the dependence of the cutting force on the depth of cut in scratch tests performed with a sharp cutter. Tests conducted in Berea sandstone and Indiana limestone confirm that the scaling of the force with the depth of cut depends on the cutting regime. They also show a dependence of the nature of the frequency distribution of the cutting force on the modes of failure.
