Abstract
An electrical discharge machining apparatus comprises a carrier and an electrical discharge machining (EDM) unit. The carrier is provided with a jig comprising a carrier plate for carrying a to-be-machined object, and the to-be-machined object is defined with a machining target area. The electrical discharge machining (EDM) unit applies a discharge energy to the machining target area through a discharge electrode with a non-uniform electric field distribution, so that the electric field is concentrated on a traveling direction. The carrier plate has an adhesive layer capable of adhering and fixing the to-be-machined object, capable of avoiding jitter of the to-be-machined object during an electrical discharge machining procedure, and capable of avoiding burrs before an end of the electrical discharge machining procedure, and making the machining target area to be located above the carrier plate to be capable of preventing the jig from hindering the electrical discharge machining procedure.
