| 摘 要： | 为提高加工Nomex蜂窝芯材料的质量和效率，采用试验方法对超声切割时的切削力进行测量，研究其影响因素和变化规律，并对切削后蜂窝芯的表面进行观察。使用回归分析法分析不同振幅和切削深度下的切削力，推导切削力的经验公式。结果显示:切削力Fy，Fz与切削深度ap，圆片刀底部边缘处振幅A呈指数关系。通过对比切削力拟合结果和试验数据，发现误差在10%内。切削后蜂窝芯表面平整、毛刺更少。

| Abstract: | 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.Resultsshow 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. |
