【摘要】：定量研究了细晶粒硬质合金刀具切削钛合金TC4过程中,不同切削参数对月牙洼磨损演变速率和磨损体积的影响。采用等高线图描绘不同切削参数下月牙洼的磨损形貌,求解月牙洼每一个磨损深度下等高线所围区域的面积,并阐述等高线所围区域面积随其磨损深度变化的关系。引入月牙洼磨损演变速率,用于表征月牙洼沿其磨损深度方向磨损的快慢程度,分析了切削参数对月牙洼磨损演变速率的影响规律。求解出不同切削参数下月牙洼的磨损体积,分析了切削速度、进给率和工件材料去除率对月牙洼磨损体积的影响规律。研究结果表明,切削速度是影响月牙洼磨损体积的主导因素。
[Abstract]:The influence of the different cutting parameters on the wear evolution rate and the wear volume of the crescent hole in the process of cutting the titanium alloy TC4 by the fine grain cemented carbide tool is quantitatively studied. The contour map is used to describe the wear morphology of the crescent depression under different cutting parameters, and the area of the contour area under each wear depth of the crescent hole is solved, and the equal height is expounded. The relation between the area of the area of the line and the change of the depth of the wear is introduced. The speed of the wear and tear of the crescent depression is introduced to describe the speed of the wear of the crescent hole along its wear depth. The influence of the cutting parameters on the wear evolution rate of the crescent depression is analyzed. The wear volume of the crescent depression under different cutting parameters is solved and the cutting speed is analyzed. The effect of feed rate and the removal rate of the workpiece material on the wear volume of the crescent depression has been studied. The results show that the cutting speed is the dominant factor affecting the wear volume of the crescent crescent.
