| Abstract: | The measuring results are with high accuracy and timeliness by high-speed ,high-precision micro-displacement laser sensor and high-frequency digital oscilloscope online measured ultrasonic vibration parameters (amplitude and frequency). Development control software can provide basic conditions for maintain the stability of the ultrasonic vibration and compound electric machining parameters on-line in real time to adjust and optimization. At the same time ,the relationship between ultrasound amplitude and ultrasonic excitation voltage is obtained by mathematical treatment. Meanwhile,the working stability of ultrasonic vibration system and technical advantages of ultrasonic compound electrical machining method are verified by using the results from analysis and tests , choosing processing parameters reasonably ,testing ultrasound machining and ultrasonic compound modulation electric machining on ceramics ,carbide and other hard and brittle difficult materials. |
