Cutting forces prediction: The experimental identification of orthogonal cutting coefficients

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