Abstract
A milling method is provided in which a finished part of any desired contour is milled from a blank of any desired contour by the milling tool being guided on a continuous, spiral guide path from the blank continuously to the finished part. In this case, material is continuously removed during the milling operation without ever lifting the tool or clamping the workpiece in place again. This results in a reduced machining time of the workpiece. The continuous, spiral guide path permits a harmonic change of form from the blank to the finished part with smooth guidance of the tool. The method can also be carried out with ceramic tools.
