摘要

A method for the machining of the workpiece surfaces on workpieces, in particular on crankshafts, in which the workpiece surface during the machining of rotating and the processing of the workpiece surface by means of at least two at a distance of adjacent, at least substantially simultaneously operating cutting of a cutting plate takes place, characterised in that the cutting plate (3, 3a to 3d) in a first method step along a first web (a) from an initial position for the plunge-cutting by turning process essentially in the axial direction to the work surface (1, 11, 12) to up to a first reference position is moved, that subsequently, the cutting plate (3, 3a to 3d) in a second process step along a direction transverse to the first web (a) the second web (b) for facing the surface of the workpiece (1, 11, 12) to a first radial desired position is moved, with the facing the surface of the workpiece (1, 11, 12) by means of the two cutting edges (3a to 3f) takes place, the at least substantially simultaneously material at the surface of the workpiece (1, 11, 12) in the case of the..
