Abstract
A sawing method and a wire saw for cutting wafers from a workpiece comprises a guidance system for the guidance of wire segments into the intended cutting planes, having at least one measuring device and at least one controlling device, the measuring device detecting an incorrect position of the wire segments in relation to the intended cutting planes by measuring the distance to a measurement point whose spatial position is dependent on the incorrect position of the wire segments, and the controlling device effecting, if necessary, a compensating movement by means of force transmission, which compensating movement brings the wire segments into the intended cutting planes.
