The invention discloses ultrasonic combined electric
machining technology real-time optimizing
control system and a control method thereof. An ultrasonic power supply is connected with a first
current sensor and a
transducer, a computer is connected with a synchronous
data acquisition card, and the synchronous
data acquisition card collects all
machining parameter data, acquired by the first
current sensor, a
voltage sensor, a second
current sensor and a
laser micro displacement sensor probe, of a
machining workpiece; the machining workpiece is placed on a
magnetic levitation workbench, a tool
electrode is fixed on the lower end face of an amplitude changing rod, the upper end of the amplitude changing rod is connected with the
transducer, the positive
electrode of a
pulse power supply is connected with a synchronous
chopper which receives chopping control signals given by a
laser micro displacement sensor controller, the synchronous
chopper is connected with the machining workpiece, working liquid is filled between the machining workpiece and the
electrode, the electrode is connected with the second current sensor through a current-limiting
resistor, the second current sensor is connected with the negative electrode of the
pulse power supply, and the
voltage sensor is connected with the output end of the
pulse power supply. The ultrasonic combined electric machining technology real-time optimizing
control system and the control method thereof have the advantages of being capable of obtaining vibration displacement, temperature, and
voltage state parameters in real time.
