Electric discharge machining apparatus |
摘要 |
An electric discharge machine apparatus has a numeric control unit which can optimally set jumping conditions without forcing the user to perform any complicated setting operation. The numeric control unit calculates an optimal jumping velocity from a value indicating a machine-allowable load for the electric discharge machining apparatus, a machining area according to the electric discharge machining conditions, and a machining gap length computed from the electric discharge machining conditions. The machining area is computed by the ratio between the proceeding velocity in machining and a discharge pulse frequency. The machining gap length is computed according to the current value of a machining current pulse as well as to a voltage loaded to the machining gap.
