Zusammenfassung:	Machining liquid is supplied until a water level of the machining liquid in a machining tank reaches a predetermined value (9) in a state where a workpiece (3) is placed on a table (2), a volume of the workpiece (3) is obtained from a difference between an amount of the machining liquid having a predetermined water level in a state where a previously calculated workpiece is not placed on the table and an amount of machining liquid supplied in the state where the workpiece is placed on the table is obtained, and a weight of the workpiece placed on the table is obtained from the obtained volume and previously stored density of the workpiece.
