摘要
在金属切削基本理论基础上,建立了超声振动钻削数学模型,基于有限元软件Third Wave Systems AdvantEdge FEM对超声轴向振动钻削过程进行有限元仿真,用Tecplot软件绘制了钻头和工件的应力曲线图和温度曲线图,主要分析了刀具和工件切削力和切削温度的变化规律。仿真结果表明在钻入一定深度后,轴向切削力在某个值上下振荡呈周期性变化,这一特性使超声轴向振动钻削从根本上改变了钻削机理,使其与传统钻削相比具有巨大的优势。研究结果对轴向振动钻削机理的研究具有一定参考意义。
Based on the principle of metal cutting,the mathematical model of ultrasonic vibration drilling was established.The finite element software Third Wave Systems AdvantEdge FEM was used to simulate the ultrasonic axial vibration drilling proces,the drill and the workpiece stress curve and temperature curve was drawn by Tecplot software,the main analysis of this paper is the tool and the workpiece’s change of cutting force and cutting temperature.The simulation results shows that after drilling a certain depth,the axial cutting force oscillates up and down at a certain value,this characteristic has fundamentally changed the traditional drilling mechanism for axial vibration drilling,making it a huge advantage compared with traditional drilling.The research results are of great significance to the study of the mechanism of axial vibration drilling.
