    Abstract:

    The ultrasonic embossing technology is a kind of new technology for the polymer microstructre fabricating. In view of the high accuracy and high reliability of micro scale ultrasonic machining system, an ultrasonic embossing system for polymer microstructure imprinting has been studied. The dynamic model of the transducer has been derived and the characteristic parameters have been solved. The finite element simulation and optimization of the device have been carried out and the experimental platform based on the force feedback control has been set up. The experimental results agree well with the theoretical model. The proposed transducer system has improved the fabrication accuracy, energy control and reliability of the microscale machining. This study provides a theoretical method for designing microscale actuator for ultrasonic embossing, and shows great potential for fast fabrication of polymer microstructures with low cost and energy consumption.
