Abstract

An eccentric circular bearing surface is machined by rotating the workpiece (3) and displacing it in a direction perpendicular to the axis of rotation until the zone to be cut encounters the cutting tool, a milling cutter (7) being used which rotates about an eccentric axis (6a). Cutter eccentricity (e) is equal to the eccentricity of the bearing surface being produced, cutter and workpiece rotate in the same sense and with equal radial velocities, and the process terminates when the normal distance (1) between the axes (6a, 3a) of rotation of cutter and the workpiece equals the sum of the cutter radius and the desired radius of the bearing surface (15).
