Abstract
A multiplicity of slices are simultaneously sliced from a workpiece during a slicing operation using a wire saw. A non-linear pitch function dTAR(WP) is selected dependent on a target thickness value function TTAR(WP), a pitch function dINI(WP) and a thickness value function TINI(WP), dTAR(WP) and adjacent grooves in the wire guide rollers are assigned a pitch at a position WP during the slicing operation, TINI(WP) slices which are obtained during a plurality of preceding slicing operations by means of the wire saw at the position WP are assigned a thickness value, dINI(WP), adjacent grooves in the wire guide rollers at the position WP are assigned a pitch during the preceding slicing operations, TTAR(WP) slices which are sliced off during the slicing operation at the position WP are assigned a target thickness value, WP denoting the axial position of the adjacent grooves with respect to the axes of the wire guide rollers.
