Material removal model of (a) peeled off, (b) shear deformation, and (c) ploughing and extruding. The formation process of the machined surface when the rounded edge radius is 20 μm and cutting thickness is (d) 0.05 mm or (e) 0.2 mm, respectively. (f) The formation process of the machined surface at a rounded edge radius of 120 μm and cutting thickness of 0.2 mm.
