Electrical discharge machining apparatus and electrical discharge machining method with adjustable machining parameters

An electrical discharge machining apparatus with adjustable machining parameters for performing a cutting procedure, comprising:

• a carrier for placing at least one to-be-machined object, the to-be-machined object being defined with a machining target area;
• and
• an electrical discharge machining (EDM) unit for cutting the machining target area of the to-be-machined object along a first cutting direction by at least one discharge electrode of the electrical discharge machining (EDM) unit with at least one machining parameter in a first cutting step of the cutting procedure, wherein the machining parameter is correspondingly adjusted when a specified parameter of the to-be-machined object changes to a first numerical value, thereby using the adjusted machining parameter to perform a second cutting step on the machining target area of the to-be-machined object,
• wherein the specified parameter comprises a first to-be-cut thickness of the to-be-machined object, the machining parameter is correspondingly adjusted when the first to-be-cut thickness of the to-be-machined object increases to the first numerical value, thereby using the adjusted machining parameter to perform the second cutting step on the machining target area of the to-be-machined object, wherein the machining parameter is an orientation parameter, when the first to-be-cut thickness of the to-be-machined object increases to the first numerical value, the electrical discharge machining (EDM) unit changes the orientation parameter from the first cutting direction to a second cutting direction, thereby performing the second cutting step on the machining target area of the to-be-machined object along the second cutting direction.
