Claim:
1. A method for milling a cutout comprising: providing a workpiece having first and second opposite sides, and a body extending between the opposite sides; providing a milling cutter having a longitudinal axis, an enveloping cylindrical surface and a front surface forming an enveloping axial surface; positioning the longitudinal axis of the milling cutter in a first orientation relative to the workpiece such that the milling cutter contacts the first side of the workpiece; using the enveloping cylindrical surface of the milling cutter when positioned in the first orientation to cut a cutout in the body of the workpiece, the cutout having a plurality of peripheral edges and rounded corners joining adjacent peripheral edges together, wherein the longitudinal axis of the milling cutter is parallel to the peripheral edges in the first orientation; positioning the longitudinal axis of the milling cutter in a second orientation, the second orientation being angled relative to the first orientation; and using the enveloping cylindrical surface and the enveloping axial surface of the milling cutter when positioned in the second orientation to further cut the rounded corners of the cutout to form sharp corners.
