Existing machine tools have extremely high requirements on the motion speed and acceleration range of each physical axis when performing the machining with the 5-axis rotary tool. Therefore, the machining of aero-engine blisks is a problem all over the world. The tool movement space is limited during machining, which makes it more difficult to achieve high machining accuracy for the blade. It is easier to achieve such machining accuracy when the surface to be machined is plane or cylindrical, but it is more difficult to achieve such machining requirements on a free-form surface. The surface of the blisk blade is mostly free-form, which puts additional extremely high requirements on the machining accuracy and surface roughness of the blade. The difficulties in manufacturing aero-engine blisks lie in the complex profile of the blade, high machining accuracy and surface quality requirements, extremely high blade machining consistency, blade machining deformation and the materials used. At present, our aero engines are less likely to use blisks, and the main reason why they are not widely available is that the technical difficulties of manufacturing the blisks are still not solved. In order to expand the application of blisks in aero-engines, difficulties in manufacturing the blisks must first be solved. The use of blisks in aero-engines is a development trend of aero-engine technology in the world.
