In this paper the cutting coefficients were identified applying the orthogonal cutting mechanics, which are used in the cutting forces and torque prediction. The experiments were performed for material combination of the workpiece (16MnCr5) and tool (HSS-E, EMo5Co5). The first step in the forces prediction acting on a cutting tool is to consider a relatively simple orthogonal cutting process in order to continue to use the results of this analysis as a base for the development of a much more general case of oblique cutting. All cutting operations share the same cutting mechanics principles, but their geometry and kinematics are different. The accepted linear forces model includes both components, due to shearing and ploughing. The total forces are calculated based on the tool geometry by summing all active discretized cutting edges.
