Abstract
An electrical discharge machining device for processing a workpiece by electrical discharges generated between a tool and the workpiece is provided. The electrical discharge machining device includes an electric discharger applying electric power to the tool and the workpiece to process the workpiece, and a vibration generator applying a vibration to the tool or the workpiece using a first voltage generated between the tool and the workpiece during a time when the workpiece is processed.
Claims6
An electrical discharge machining device for processing a workpiece by electrical discharges generated between a tool and the workpiece, the electrical discharge machining device comprising:
- a power supply configured to supply electric power to the tool and the workpiece to process the workpiece, wherein a resistor is connected in series between the power supply and the workpiece;
- an actuator configured to generate a vibration to be applied to the tool or the workpiece;
- and
- an amplifier connected to both terminals of the resistor to receive a first voltage generated between the tool and the workpiece during a time when the workpiece is processed, use a second voltage occurred at the resistor as an input voltage, amplify the input voltage to a level required to drive the actuator, and transmit the amplified input voltage to the actuator to apply the vibration to the tool or the workpiece.
