| 摘 要： | 在纳米级车削表面形成中刀具和工件间的相对振动为主要影响因素之一.现有相对振动的研究方法包括谱分析法、直接测量法和切削力分析法,均不能同时满足真实反映切削过程中的相对振动和很好地预测表面粗糙度的要求,致使纳米级表面粗糙度的预测精度较低.针对上述问题,通过分析和提取单点金刚石车削已加工表面轮廓数据、定义等效振幅的概念和计算...

| Abstract: | The relative tool-work vibration is one of the dominating factors in forming nano-scale surface,which is generally studied by using spectrum analysis method,direct measuring approach and cutting force method.However,all of them cannot be used to predict surface roughness and cannot gain the true vibration information in cutting process simultaneously,which impacts the prediction accuracy of surface roughness.In order to solve the issues,a new method of extracting and measuring relative tool-work vibration i... |
