[0002] At present, the complexity of my country's manufacturing products is getting higher and higher, especially the products in the fields of aerospace, military industry, etc. need to process complex curved surfaces, which requires the machine tool to have more than five axes including two rotary axes. A five-axis linkage machine tool refers to a machine tool with at least five coordinate axes, including three linear coordinates (X, Y, Z) and two rotational coordinates (generally two of A, B, C, depending on the structure of the machine tool), and these coordinate axes can be coordinated and processed at the same time under the control of the computer numerical control (CNC) system. When the workpiece is placed on the machine tool workbench, the control system will control the movement of the five coordinate axes at the same time according to the preset processing program, so that the tool can process the workpiece according to the predetermined trajectory. This coordinated movement enables the five-axis linkage machine tool to complete the processing tasks of complex curved surfaces, such as three-dimensional curved surface engraving, spiral surface processing, etc.
