A method for the machining of the workpiece surfaces on workpieces, in particular on crankshafts, as well as cutting insert for carrying out a method of this type

摘要

A method for the machining of the workpiece surfaces, in particular of workpiece surfaces on crankshafts, in which a first, second and third workpiece surface (3, 4, 5) by machining with a cutting plate (1, 1 '', 1 ", 1"'') are machined, with the workpiece surfaces rotate during the machining operation, with the following steps: the cutting plate (1, 1 '', 1 ", 1"''), in a first process step, along a first feed path (a, c) for facing the first workpiece surface (3; 4) is moved to a first desired position, wherein the facing by means of a cutting edge (1a, 1p; 1d, 1q; 1i, 1q) takes place, in a second process step along a second feed path (b) for processing of the second workpiece surface (5) to a second target position is moved, with the machining by means of at least two in the direction of the feed path lying next to one another at a distance substantially simultaneously operating cutting edges (1a to 1d; 1a to 1i) takes place, and in a third process step along a feed path (c) for the processing of a third workpiece surface (3; 4) to a third desired position, wherein the processing by means of a cutting edge (1p, 1q; 1d, 1q; 1i, 1q) takes place.
