Airfoil machining method and cutting tools

摘要

A method of machining an airfoil includes the steps of providing first and second cutting tools respectively having first and second cutting contours that are different than one another. A blank is cut with the first cutting tool to provide a first airfoil surface on a first blade. The blank is cut with the second cutting tool to provide a second airfoil surface on a second blade. An airfoil is produced having the first and second blades. A cutting tool for machining the airfoil includes a shank. A cutting surface adjoins the shank and provides a cutting contour corresponding to an airfoil surface. The cutting surface extends along a cutting length axially from a nose to near a cutting boundary. The cutting length is configured to be greater than the blade length.
