Claim of US Patent No. 10,780,513

1. A wire electrical discharge machining system including a holding unit that holds a workpiece to be machined by wire electrical discharge machining and a robot that changes the workpiece on the holding unit, that inspects the workpiece after the wire electrical discharge machining, or that inspects a cut-out portion cut out from the workpiece by the wire electrical discharge machining,the wire electrical discharge machining system comprising:
a securing device, wherein the securing device is placed, when the wire electrical discharge machining has been performed on the workpiece held on the holding unit to reach a predetermined position before completion of the machining, at a cut position where the wire electrical discharge machining has been performed, and the securing device simultaneously individually attracts a cut-out portion of the workpiece and a remaining portion of the workpiece at the cut position where the workpiece has been cut, thereby the securing device secures the cut-out portion to the remaining portion,
wherein the robot is configured to cause the securing device to individually attract the cut-out portion and the remaining portion.
