Claim:
1. A method for performing a milling operation, the method comprising: providing a milling cutter and a workpiece having a non-machined workpiece surface; receiving, at a computer, a set of milling cutter geometry parameters; creating, at the computer, a curvilinear profile from the workpiece surface; extracting, at the computer, a radius parameter from the curvilinear profile; determining, at the computer, an initial step-over value in response to the set of milling cutter geometry parameters; determining, at the computer, 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 value of a cutter inclination angle; determining, at the computer, a minimum surface roughness value in response to the cutter inclination angle value; adjusting, at the computer, the cutter inclination angle value in response to the minimum surface roughness value; adjusting, at the computer, a calculated step-over value in response to the minimum surface roughness value; and positioning the milling cutter traveling along the workpiece using the calculated step-over value and the adjusted cutter inclination angle value.
