| Summary: | Machine chatter phenomenon has a great influence on the stability during the machining process of the machine tool. It has a great limitation on the machining efficiency of the machine tool and the machining accuracy of the product. The flutter of a machining center will appear when a certain machining center reaching a particular speed. The chatter will occur at a specific frequency. With the increase in the depth of cutting and the spindle speed, the value of chatter frequency will have complex changes; through the vibration test, it was confirmed that the two chatter frequencies are the natural frequencies of the product system and the spindle system, respectively. Improve the optimisation parameters and propose ways to suppress chatter.
