摘要
采用超声钻孔能够有效缓解轴向力作,提升孔屑排斥效果.为了提高镍基高温合金的钻孔质量,以Inconel 718镍基高温合金为例开展超声低频振动辅助钻孔试验研究,完成系统超声低频振动测.钻孔试验结果表明:相比较普通钻孔,超声低频振动钻孔的轴向力与扭矩均值相对常规钻孔方式下降比例为10％～15％;超声低频振动钻孔原先螺旋切屑转变为许多断屑物,促进断屑并快速排出,获得稳定钻孔效果.该研究对提高Inconel 718镍基高温合金板的钻孔质量具有很好的实际应用价值.
Abstract
The use of ultrasonic drilling can effectively alleviate the axial force and improve the effect of hole chip repulsion.In order to improve the drilling quality of nickel-based superalloy,Inconel 718 nickel-based superalloy was taken as an example to carry out the ultrasonic low-frequency vibration assisted drilling test and complete the ultrasonic low-frequency vibration measurement system.The results of drilling test show that compared with ordinary drilling,the mean value of axial force and torque of ultrasonic low-frequency vibration drilling decreases by 10％～15％.Ultrasonic low frequency vibration drilling the original spiral chip into a lot of chip breaking,promote chip breaking and rapid discharge,to obtain a stable drilling effect.The research has good practical application value for improving the drilling quality of Inconel 718 nickel based superalloy plate.
