Electrical discharge machining apparatus and method of the same

An electrical discharge machining apparatus for performing an electrical discharge machining procedure on at least one to-be-machined object, at least comprising:

• at least one carrier for carrying the to-be-machined object, the to-be-machined object being defined with at least one machining target area;
• and
• at least one electrical discharge machining unit, comprising at least one electrical discharge electrode and a power supply unit, wherein the power supply unit provides an electrical discharge energy to the electrical discharge electrode with an electrical discharge frequency, and the electrical discharge machining unit performs the electrical discharge machining procedure on the machining target area of the to-be-machined object through the electrical discharge electrode with at least one machining parameter, wherein the electrical discharge machining unit adjusts an actual output energy value correspondingly according to a changing status of the electrical discharge frequency or the electrical discharge energy during an electrical discharge process of the electrical discharge machining procedure, so that the electrical discharge machining procedure maintains in a target machining status.
