Claim:
1. A method of machining a workpiece comprising: rotating the workpiece around a workpiece axis and at a workpiece rotational speed N rotating a tool having at least one cutting surface around a tool axis and at a tool rotational speed NT so that the at least one cutting surface has a tool surface velocity V positioning the tool axis at a fixed location relative to the workpiece axis so that the at least one cutting surface engages the workpiece at multiple circumferential locations around the periphery of the workpiece as the tool and workpiece are rotated, wherein, with the tool axis at the fixed location, the workpiece and the tool are rotated for a sufficient duration so that the tool traverses multiple rotational passes around the periphery of the workpiece while the workpiece and the tool engage at the multiple circumferential locations; controlling the tool surface velocity V controlling the workpiece rotational speed N
