Abstract
A tool for abrading workpieces having random, convex, concave, planar or curved surfaces has a conically convex end face. When working a workpiece, the tool acquires an inclination transversely to the feed direction, so that the tool with the contact line is located on the workpiece. This leads to the same conditions as exist in the rotary milling of convexly curved surfaces when machining concave surfaces of the workpiece. Finest surface characteristics are obtained on the workpiece by the tool and the method of machining with this tool.
