| 摘要 |
An electro discharge machining apparatus comprises an electrode configured to machine a desired feature in a workpiece, a pulse generator configured to energize the electrode and the workpiece to opposite electrical polarities, a machining solution source configured to pass a machining solution between the electrode and the workpiece, and a servomotor configured to drive the electrode to move relative to the workpiece. The electro discharge machining apparatus further comprises at least one detection element configured to detect machining signals, and a controller. The controller controls the pulse generator and the servomotor to machine the workpiece according to a plurality of first process parameters predetermined therein and analyzes the detected machining signals to generate a first response signal to activate a plurality of second process parameters predetermined therein and different from the first process parameters to machine the workpiece. An electro discharge machining method is also presented.
