摘要：
An electric discharge machine includes a pulse determining section, which determines whether an electric discharge pulse is an effective electric discharge pulse contributing to machining or an ineffective pulse not contributing to machining, a pulse counting section, which counts the number of electric discharge pulses determined to be effective electric discharge pulses, a machining speed measuring section, which measures the machining rate in the axial direction, a dividing section, which divides the total number of electric discharge pulses by the machining rate in the axial direction, a storage section, which stores predetermined constant data corresponding to electric conditions such as a waveform for a current due to materials of an electrode and a workpiece or generation of electric discharge, and a machined area computing section, which computes a machined area according to the divided data and the stored constant data. A method for controlling the electric discharge machine is also described.
