摘要

The milling tool is guided along a continuous guide path (7) from the outside contour of the raw blank (1) to the contour (2') of the finished part (2) and the raw blank is constantly changed in shape to form the finished part with a constant discharge of material. The continuous path is formed as a two dimensional, flat, spiral-shaped path or as a three dimensional spiral-shaped path. Independent claim describes process for producing continuous guide path by first producing auxiliary lines which run equal to electrostatic field lines (3) between the profile of the finished part and the profile of the raw blank.
