为了提高发动机缸体与缸盖结合面的表面加工质量，研究了铣削加工过程中的颤振稳定性问题。进行了刀具—主轴锤击模态试验和铣削力仿真实验，获得了所用刀具的低阶模态参数及铣削力系数。构建了铣削颤振的稳定性叶瓣图，用于指导切削参数的选择和优化。通过该方法可以选取合适的主轴转速和切削深度，避免加工过程中颤振的发生，提高工件表面的加工精度，并对加工刀具及机床本身有保护作用，可提高其使用寿命。

High quality on the joint face between the engine cylinder block and head is required. Chatter sta-bility problems of milling process are analyzed. Hammer modal test and milling force simulation experiments are conducted to get the low modes’ parameters and the milling force coefficient of the tool. Cutter chatter stability lobe diagram is built to guide the selection and improvement of cutting parameters. We can select the appropriate spindle speed and depth of cutting through this method, avoiding the occurrence of chatter behavior. It can keep the required accuracy of the workpiece. At the same time, it can protect the tool and machine to improve their service life.
