Abstract

An inverse method is presented for estimating the shear stress in the work material in the region of chip-tool contact along the rake face of the tool during orthogonal machining. The method uses an estimate of the temperature of the work material as it exits the primary shear zone, an experimental measurement of the peak temperature in the work material along the tool-chip interface, and a two-zone empirically based contact model for friction along this interface. It is also shown how the method can be generalized to provide an estimate of the stress, given an perimentally determined discrete set of steady-state temperature measurements along the rake face of the tool, even when no friction model is specified.
