N2 - This paper presents investigations on machining of a nickel-based alloy. Orthogonal cutting tests using uncoated carbide inserts with 10 and 25 micron edge radius and 0 and 3 degree tool rake angles are performed. Forces, chip geometry and tool edge conditions are measured. An analytical model is introduced to identify average strain, strain rate, shear stress and temperature for segmented chip formation and friction conditions exerted on the tool during cutting process. Johnson-Cook material model related flow stress data are modified using the experimental data. Finite Element simulations are conducted to investigate the influence of tool geometry on predicted stress, strain and temperature distributions on machined surfaces.
