In the electric discharge machining, supplied pulse form of machining energy is important factor for improvement of machining characteristics, exclusion of machining defects, etc. Though a lot of supplied pulse form of machining energy can be assumed, the problem of trouble some or easy to generate and supply practically is important matter. Further, in investigation of thermal process to electrode, it is necessary to consider the effects of remaining heat after over supplied machining energy. Considering these two points, the thermal process (melting form, condition of stress distribution and depth of generated crack) are calculated by means of Monte Carlo method, in the cases of some energy pulse forms which are superimposed triangular pulse form on rectangular pulse form.
In consequence, many of informations that will be required to machining experiments, were obtained. In general meaning, it became clear the energy supplied pulse form superimposed triangular pulse form, which rising and falling inclinations are equal, is more advantageous in the point of machining characteristics and machining defects.
