摘要： To improve the quality and efficiency of Nomex honeycomb material, actual experiments are used to test the cutting force during ultrasonic cutting.The influencing factors and changing laws of the force are studied.The surface of honeycomb is observed after cutting.Regression analysis is used to research the cutting forces at different amplitudes and cutting depths.An empirical formula is derived.Results show that there is a index relationship between cutting forces (Fy and Fz) and cutting depth ap and the amplitude A at bottom edge of blade.It is found that there is within 10% error between actual and simulating forces, and the surface of cutting honeycomb is flat with less veining.
