The control technology of five-axis linkage machining technology, such as interpolation algorithm and coordinate transformation, has been developed very mature. The technical difficulty of five-axis linkage machining center still lies in its structural design. Although in theory, CNC machine tools with five-axis linkage function can process structural parts, blades, impels or blades, but the processing efficiency, processing accuracy of different machine tools, and even the number of card loading are very different.

The five-axis linkage machining center suitable for the aviation industry should have high static and dynamic rigidity to withstand the cutting force during heavy cutting. Long tool life results from stable, low-vibration cutting — a key factor in low-cost machining. The structure of the five-axis linkage machining center used in the aviation manufacturing industry should adapt to the characteristics of the aviation parts processing technology, such as the use of horizontal machining center processing structural parts, a cuboid column can be installed on the tray, and the workpiece and fixture are fixed on the four sides of the column. In this way, four workpieces can be processed at a time, and chip removal is very convenient.

Another example is the processing of aero engine blades, the hair embryo is usually a thin-wall forging of titanium alloy, which needs to have a "pull" effect on the workpiece when loading the card to improve the rigidity of the hair embryo. When machining the inlet or outlet edge of the blade, the tool is quickly converted in the back arc and the inner arc surface, if the machine structure is designed so that the tool tip is located in the center of the swing axis or near, the compensation motion of the other axis will be avoided or greatly reduced, thereby improving the processing efficiency and accuracy.
