Abstract
A method cuts slices from workpieces using a wire saw with a wire array tensioned in a plane between two wire guide rollers supported between fixed and floating bearings. A workpiece is fed through the wire array perpendicular to a workpiece axis and the wire array plane. The workpiece is fed through the wire array while controlling a temperature of the workpiece with a cooling medium, with simultaneous axial movement of the floating bearings by adjusting a temperature of the fixed bearings in dependence on a depth of cut and in correlation with a first correction profile, and while simultaneously moving the workpiece along the workpiece axis in accordance with a specification of a second correction profile, which specifies a travel of the workpiece. The first correction profile and the second correction profile being opposed to a shape deviation.
