摘　　要：为了探究二维超声振动对6061铝合金薄壁管件车削温度的影响,建立了二维超声振动车削热模型,并利用自主研发的车刀对6061铝合金圆筒外表面进行了加工,研究了加工过程中切削温度随切削参数和超声振幅的变化规律。结果表明:二维超声振动车削6061铝合金圆筒时的切削温度比普通车削的切削温度低,并且随着进给量、切削深度以及超声振幅的增加,切削温度整体都呈现出减小的趋势。In order to investigate the effect of two-dimensional ultrasonic vibration on the turning temperature of 6061 aluminum alloy thin-walled pipe fittings,a two-dimensional ultrasonic vibration turning thermal model was established.The outer surface of 6061 aluminum alloy cylinder was machined by using independently developed turning tools,and the variation of cutting temperature with cutting parameters and ultrasonic amplitude during the machining process was studied.The results show that the cutting temperature of two-dimensional ultrasonic vibration turning 6061 aluminum alloy cylinder is lower than that of ordinary turning,and the overall cutting temperature shows a decreasing trend with the increase of cutting depth,feed rate,and ultrasonic amplitude.
