Summary:A method for performing a milling operation includes providing a milling cutter and a workpiece having an non-machined workpiece surface; receiving a set of milling cutter geometry parameters; creating a curvilinear profile from the workpiece surface; extracting a radius parameter from the curvilinear profile; determining an initial step-over value in response to the set of milling cutter geometry parameters; determining a surface roughness value in response to the set of milling cutter geometry parameters, the curvilinear profile of the workpiece surface, the radius parameter, and an initial tool inclination angle; determining a minimum surface roughness value in response to the cutter inclination angle value; and adjusting a calculated step-over value in response to the minimum surface roughness value where the calculated step-over value and the calculated inclination angle value are applied to operating the milling cutter.
