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 effects of cutting parameters on the developing rate and volume of crater wear of uncoated cemented carbide tool during turning of TC4 alloy are investigated. Contour maps are used to describe the crater morphologies and study the relationship between the area of contour region and its wear depth in the case of the different cutting parameters. The evolution rate of crater wear is introduced to describe the variation rate of the area of contour region with its wear depth. The effects of cutting parameters on the developing rate of crater wear are analyzed. The volume of crater wear is obtained in the case of the different cutting parameters, and the effects of cutting speed, feed rate and material removal rate on the volume of crater wear are analyzed. The research result shows that the cutting speed is the primary factor in determining the volume of crater wear. Key
