Multiple milling on crankshafts

Process for the metal-removing machining of surfaces on a workpiece (WST) which is chucked on a central axis of the workpiece (Z1-axis) such that the workpiece can rotate (C-axis) in a defined manner, the metal-removing machining being carried out by milling, comprising the steps of:

• machining the workpiece (WST) simultaneously on at least first and second machining surfaces, a form and/or rotational position of which, with respect to the central axis (Z1), do not coincide, at least one of said machining surfaces being eccentric with respect to the central axis of the workpiece, and
• machining each at least first and second machining surface by separate, at least first and second milling cutters (WZ1, WZ2, ...), each of which can only move in a movement path which is transverse to the workpiece (WST), and each of which operates independently and separately from the other,
• controlling the rotational parameters of the workpiece (WST) with regard to rotational position, rotational speed (nwst) and direction of rotation taking into account movement parameters, the movement parameters being transverse movements and rotational speeds of each of the at least first and second milling cutters (WZ1, WZ2, ...) at a particular point in time, and controlling transverse movement and rotational speed (n1, n2, . . .) of each of the at least first and second milling cutters (WZ1, WZ2), separately and independently of each other, on the basis of the rotation of the workpiece (WST).
