磨削颤振是在磨削过程中产生的,因振动所需的能量来自磨削过程,是一种自激振动。它严重地影响着磨制的稳定性。磨削过程的自激振动可以用图1来表示。这是一个闭环系统:磨削深度的变化通过磨谢过程引起磨削力的变化却,而却又通过机床的弹性系统变成砂轮与工件间的相对位移议如此 Chatter chatter grinding is generated in the grinding process, because the energy required for vibration from the grinding process, is a self-excited vibration. It severely affects the stability of the mill. Self-excited vibration grinding process can be expressed in Figure 1. This is a closed-loop system: changes in depth of cut change the grinding forces caused by the wear-in process, but then through the elastic system of the machine becomes the relative displacement between the grinding wheel and the workpiece
