Method for optimized milling close to the final contour

Abstract

A method for optimized milling of workpieces close to the final contour, in particular chamfers on turbine blades, is disclosed. The method is characterized in that a numeric optimization method is provided for the automatic control of the kinematic sequences of motion, wherein an additional rotation around an axis parallel to the tool axis is optimized in terms of kinematic and/or kinetic and/or workpiece-specific manufacturing criteria. With the method, it is possible to achieve optimum results in the milling of chamfers close to the final contour or in the deburring of workpiece edges. In this case, the method makes it possible in particular to make available a path optimization that is required in order to achieve an optimum processing result, wherein this optimization is preferably automated and can take place within a short time. In addition, the inventive method achieves a high level of series stability in manufacturing.
