摘要:
A method resumes an interrupted process for sawing a workpiece into wafers using a wire saw that includes advancing a wire web into existing sawing kerfs of the workpiece with a forward movement of the sawing wire with a first speed in the presence of a liquid sawing medium until the wire web or workpiece has reached a position corresponding to the interruption of the wire sawing process. The sawing wire is moved in defined time intervals by a forward movement of a particular length with a second speed and a backward movement of another length with a third speed, where the backward length is less than the forward length and the forward and backward movement correspond to a cycle. The wire length that is unwound during the forward movements is increased until the length during the forward movement corresponds to the length of the forward movement before the interruption.

一种方法恢复中断的过程,用于使用线锯将工件锯切成晶片,该线锯包括在存在液体锯切介质的情况下以一级速度向前移动金属丝网到工件的现有锯切切口中,直到 丝网或工件已经到达与切线过程中断相对应的位置。 通过具有第二速度的特定长度的向前移动和具有第三速度的另一长度的向后移动,锯齿线以规定的时间间隔移动,其中后向长度小于前进长度,并且向前和向后移动对应于 到一个循环。 在向前运动期间解开的线长度增加,直到向前运动期间的长度对应于中断之前的向前运动的长度。
