ABSTRACT:
An electrical discharge machine is provided with at least one weight measuring apparatus for detecting the weight of one or both of an electrode and a workpiece, and a control unit for selecting or controlling the working conditions in response to the output of the weight measuring apparatus. The weights of the electrode and the workpiece are measured after the working operation has been interrupted temporarily, or while continuing the working operation. Well-known various accurate balances or force measuring apparatuses may be used as the weight measuring apparatus. A microcomputer including a numerical control unit may be used as the control unit.
