| 摘 要： | 通过微元铣削力与瞬时未变形切屑厚度之间的线性关系,提出了螺旋圆柱铣刀的瞬时切削力模型.在此基础上,采用两自由度弹性-阻尼系统,建立了适合薄壁零件的综合考虑刀具子系统和工件子系统动态特性的动态铣削力模型.最后通过实际测量数据与模型计算数据的对比,验证了提出的动态铣削力模型的有效性.

| Abstract: | The cutting force is one of the most important parameters for milling process. This paper sets up an instantaneous cutting force model for a spiral cylinder cutter by analyzing the linear relationship between micro-unit milling force and instantaneous uncut chip thickness. Based on it, a dynamic force model for milling process of thin-walled parts is established using a two-freedom elastic-damping system by considering the dynamic characteristics of the tool subsystem and the workpiece subsystem. The experimental result proves that the proposed dynamic milling force model for high-speed milling of thin-walled parts is effective. |
