Abstract
In an ingot cutting apparatus that cuts an ingot using a plurality of stretched wires, load sensors are provided on the new wire side and the old wire side of the ingot, and loads applied to the new wire side and the old wire side of the ingot are measured using the load sensors on the new wire side and the old wire side. When measuring the loads, for example, the center of moment about the X-axis that is the running direction of the wire is calculated. When the deviation from the center of gravity of the ingot is greater than or equal to a reference value, notification for replacement of the wire, control of the conveying speed of the wire, control of the pressing speed of the ingot, and so forth are performed through a control unit.
