Research on Ultrasonic Cutting Acoustic System of Machining Nomex Honeycomb Material

Zhang Yundian;Xiao Jianxiong;Fang Liang;Lu Zhiping;Hangzhou Dianzi University;  
According to the principles of ultrasonic machining,a new type of CNC ultrasonic cutting spindle of cutting Nomex honeycomb materials was designed.The acoustic horn was designed by the four-end network method,and the acoustic horn was also analyzed and corrected by FEM.The finite element model of ultrasonic acoustic system was established and analyzed.According to the diagram,the displacement of horn flange changes little,the output amplitude is larger.The amplitude of the cutter was measured by laser detector,and was worked out a=22.37μm that meets the processing requirements.A large of experiments of cutting Nomex honeycomb materials using the ultrasonic cutting spindle was carried out,and the results are significant:smooth processing surface,high processing precision,no dust in machining process.
