| 摘 要： | 在振动钻削加工原理的基础上建立振动钻削过程中平均摩擦力的数学模型,分析动载荷对平均摩擦力的影响规律。在超声振动钻削试验装置上对0Cr17Ni4Cu4Nb不锈钢进行了普通钻削和超声振动钻削试验,对比分析了孔壁表面粗糙度、钻头磨损形貌和切屑形状。结果表明:超声振动钻削能够减少平均摩擦力;通过观察加工后钻头与孔的表面形貌,超声振动钻削钻头磨损程度低,孔壁表面粗糙度值小,具有更好的断屑、排屑性能。

| Abstract: | Based on the principle of vibration drilling, the mathematical model of average friction force during vibration drilling was established, and the influence law of dynamic load on average friction was analyzed. Ordinary drilling and ultrasonic vibration drilling tests were carried out on the 0Cr17Ni4Cu4Nb stainless steel on the ultrasonic vibration drilling test device. The surface roughness of the hole wall, bit wear morphology and cutting shape were compared and analyzed. The test shows that ultrasonic vibration drilling can reduce the average friction force; by observing the surface morphology of the drill bit and the hole after processing, the ultrasonic vibration drilling bit has low wear degree, the surface roughness value of the hole wall is small, and has better chip breaking and row discharge. |
