This paper presents a new methodology to study the orthogonal cutting mechanism based on the displacement and temperature fields obtained by the particle image velocimetry technique and thermal infrared imager, respectively. With the displacement and temperature fields as inputs, the thermo-elasto-viscoplastic constitutive model is adopted to calculate the orthogonal cutting strain and stress fields. The formation of built-up edge is detected using the velocity fields. The geometries of the primary shear zone for two different cutting speeds are determined by the strain rate field. The shear stress distributions along the shear plane are obtained according to the calculated results.
