Claim Text:
1. A method for machining an elongate, non-rotationally symmetrical workpiece, wherein a first clamping point for a first end of the workpiece and a second clamping point for a second end of the workpiece are provided, and the workpiece is supported by a steady rest, which has clamping elements for clamping the workpiece on a non-rotationally symmetrical cross section, comprising: after clamping the workpiece between the first and the second clamping point, moving the steady rest with its open clamping elements along the longitudinal axis of the workpiece into a supporting position; and during movement of the steady rest into the supporting position and/or while changing the supporting position of the steady rest, preventing a collision between the open clamping elements of the steady rest and the workpiece by way of a program-controlled rotation of a rotary part of the steady rest.
