Abstract:
1. A method for simultaneously slicing a multiplicity of wafers from a substantially circular-cylindrical workpiece that is connected to a sawing strip, the method comprising: executing a relative movement between the workpiece and a wire gang of a wire saw in a direction perpendicular to a longitudinal axis of the workpiece with the aid of a forward feed device with a defined forward feed rate, by which the workpiece is guided through the wire gang so as to be sliced into a plurality of wafers; and varying the forward feed rate through the course of the method including: setting the forward feed rate to a value v after reaching the cutting depth of 50% , increasing the forward feed rate to a value v subsequently to increasing the forward feed rate to the local maximum, decreasing the forward feed rate to a value v subsequent to coming into contact with the sawing strip, increasing the forward feed rate to a value v
