发明名称 円筒形の被加工物から多数のウェハを同時にスライスするための方法
摘要 <p>A method for simultaneously slicing a multiplicity of wafers from a substantially circular-cylindrical workpiece that is connected to a sawing strip includes executing a relative movement between the workpiece and a wire gang of a wire saw with the aid of a forward feed device with a defined forward feed rate so as to slice the wafers. The forward feed rate is varied through the course of the method and includes being set to a value v1 at a cutting depth of 50% of the workpiece diameter. Subsequently, the forward feed rate is to a value v2>1.15×v1 as the forward feed rate passes through a local maximum. The forward feed rate is set to a value v3<v1 when the wire gang first comes into contact with the sawing strip. The forward feed rate is increased to a value v5>v3.</p>
