整体叶盘作为航空发动机内的高速旋转零件，在其工作中通常需承受较大的载荷

As a high-speed rotating part in an aero-engine, the integral blisks usually need to bear larger loads and higher temperatures during its work. Therefore, the various characteristics of the integral blisks: the back of the leaf pot, the root of the leaf, and the air intake and exhaust edges. The machining accuracy, surface quality and machining efficiency have all put forward extremely high requirements. In the actual factory, when CNC polishing a certain feature of an integral blisk, the craftsman uses random test tools to determine which polishing tool to use, and uses his own experience to determine the motion parameters of the machine tool. This method can range from several days to several Compared with manual polishing, it is inefficient compared with manual polishing. There are many serious problems with the polishing parameters obtained by the craftsmen through experience. This is because there are many factors that restrict the process parameters, and their influence on the polishing process is intricate and complicated. It's ever-changing, and it's difficult to grasp it through experience. Moreover, the uncertainty of the current tool parameters and the over-polishing or under-polishing caused by unstable polishing methods will irreversibly affect the polishing quality and directly determine the life of the engine. We need to take the instability of this tool and workpiece through theory Optimize the method established with the mathematical model, quantify the workers’ experience, and improve efficiency and economy on the basis of ensuring that the processing quality meets the requirements and is stable.

As a high-speed rotating part in aero-engine, blisk usually needs to bear large load and high temperature in its work. Therefore, the machining accuracy, surface quality and processing efficiency of Blisk are required for the characteristics of blisk, such as blade basin, blade root, inlet and exhaust edge. In the actual factory, when CNC polishing a certain feature of an integral blisk, the technologist uses the method of random test tools to determine what polishing tool to use, and uses their own experience to determine the motion parameters of the machine tool. This method is less than a few days and more than a few months. Compared with manual polishing, there are many serious problems in the polishing parameters obtained by the technicians with their experience Because there are many factors restricting the process parameters, their influence on the polishing process is complex, and the structure of the workpiece is changeable, so it is difficult to grasp it by experience. Moreover, the uncertainty of tool parameters and the over and under polishing caused by unstable polishing methods will have an irreversible impact on the polishing quality, which directly determines the life of the engine. We need to optimize the instability of the tool and workpiece through the way of theoretical and mathematical model establishment, and quantify the experience of workers, so as to ensure that the processing quality meets the requirements and is stable On the basis of this, the efficiency and economy are improved.<br>
