Abstract
A system for ultrasonic assisted electrical discharge machining of a component part having a longitudinal axis, a half wavelength resonant frequency along the longitudinal axis and an attachment portion, is provided. The system includes an ultrasonic horn having a longitudinal axis, a half wavelength resonant frequency along the longitudinal axis and an attachment portion. The half wavelength resonant frequency of the ultrasonic horn is the same as the half wavelength resonant frequency of the component part. Additionally, one of the attachment portion of the component part and the attachment portion of the ultrasonic horn is a male part and the other one of the attachment portion of the component part and the attachment portion of the ultrasonic horn is a female part sized and shaped to mate and engage one another when the component part and the ultrasonic horn are at generally the same temperature.
