放电加工机
摘要：
本发明提供一种放电加工机。在将被加工物载置在工作台的状态下，供给加工液直到加工槽内的加工液水位成为预定高度为止，根据预先计算出的在没有将被加工物载置在工作台的状态下成为预定水位的加工液的量与将被加工物载置在工作台的状态下所供给的加工液的量之间的差，求出被加工物的体积，根据求出的体积和预先存储的被加工物的密度，求出载置在工作台的被加工物的重量。按照与被加工物同样的步骤，求出被加工物安装用夹具的重量，将夹具载置在工作台并用夹具固定了被加工物的状态下求出夹具和被加工物的总体积，取得与夹具的体积的差，由此求出被加工物的体积，根据求出的体积和预先存储的被加工物的密度，求出固定在夹具上的被加工物的重量。
摘要（英）：

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.
