一、前言金属切削机床加工过程的动态稳定性不仅与机床本身的动态特性有关,而且与切削速度、主轴转速、切深、进给速度,刀具的材质和几何参数以及工件的几何形状等切削条件也有关。在加工中为了获得机床切削过程的稳定性,保证工件的精度和表面光洁度的要求,通常按机床切削稳定边界图来选择加工条件。这种稳定边界图,有时也称梅律特(Merrit)图,明确地提供了绝
I. Introduction The dynamic stability of the metal cutting machine tool machining process is not only related to the dynamic characteristics of the machine itself, but also with the cutting speed, spindle speed, cutting depth, feed rate, the material and geometry of the tool and the geometry of the workpiece and other cutting conditions Also relevant. In the process of machining in order to obtain the stability of the cutting process to ensure the accuracy of the workpiece and the surface finish requirements, usually according to machine cutting stable boundary map to select the processing conditions. This stable border map, sometimes called the Merritt chart, explicitly provides the absolute
