【摘要】 为探究旋转超声磨边在瓷砖加工中的应用,使用ANSYS软件对旋转超声磨边机床的超声振子进行模态分析,发现谐振时工具头把纵向振动分解为纵向和径向振动。搭建了旋转超声磨边机床,包括旋转超声磨边主轴和四轴运动测试平台。并且使用机床研究了有无超声情况下主轴转速和进给速度对轴向磨削力的影响。结果表明:在瓷砖磨边过程中,低主轴转速下添加超声振动可减小轴向磨削力;不同进给速度下,旋转超声磨边的轴向磨削力比传统磨边小。更多还原

【Abstract】 In order to explore the application of rotary ultrasonic edging in tile processing,the ANSYS software was used to analyze the ultrasonic oscillator of the rotary ultrasonic edging machine. It was found that the tool head decomposed the longitudinal vibration into longitudinal and radial vibrations during resonance. A rotary ultrasonic edging machine was built,including a rotating ultrasonic edging spindle and a four-axis motion test platform. The machine tool was used to study the influence of the spindle speed and feed rate on the axial grinding force with or without ultrasonic. The results show that the addition of ultrasonic vibration at low spindle speed can reduce the axial grinding force during the edging process of the tile.The axial grinding force of the rotating ultrasonic edging is smaller than the conventional edging at different feed speeds.更多还原
