Claim Text:
1. A method for roller burnishing a cylindrical component part surface of a workpiece comprising: using a roller burnishing tool including at least one rolling element, wherein the at least one rolling element is pressed by hydrostatic pressurization radially outwardly against the component part surface and is left to roll down the component part surface by rotating the roller burnishing tool or the workpiece; detecting torque or a measured value representing the torque which arises as a result of friction between the at least one rolling element and the component part surface; supplying the detected torque or measured value representing the torque for evaluation; and determining whether the detected torque or measured value representing torque indicates that the at least one rolling element is rolling or sliding with respect to the component part surface based on the evaluation.
