Abstract:
A method for cleaving a plate-shaped workpiece formed with two or more linear recesses into three or more parts includes: a first positioning step of holding the workpiece by a positioning unit in place to position a first linear recess; a first clamping step of clamping one side of the first linear recess by a fixing clamp and the other side by a rotating clamp; a first cleaving step of moving back the positioning unit and rotationally separating the rotating clamp; a second positioning step of releasing the clamps and causing the positioning unit to position a second linear recess; a second clamping step of clamping one side of the second linear recess by the fixing clamp and the other side by the rotating clamp, and a second cleaving step of moving back the positioning unit and rotationally separating the rotating clamp.
