One of the advantages of the multi-axis machine tool is that the one-time clamping of parts can be realized through the selection of a workbench or the swinging of a main shaft of the multi-axis machine tool, and the machining of multiple surfaces and multiple elements is completed. Especially, the critical position sizes of complex parts and critical parts with high precision can be clamped once through the multi-axis machine tool. Especially for five-axis machine tools, the one-time clamping of the workpiece is realized by the 3+2 positioning and five-axis linkage of the structures such as spindle swing or workbench rotation or the mixed rotation of the spindle swing and the workbench during the processing of the parts. Therefore, for a five-axis machine tool, the dynamic accuracy requirement is high, and particularly for the five-axis machine tool, the one-time clamping of a workpiece is realized due to the 3+2 positioning and five-axis linkage of the structures such as spindle swing or workbench rotation or the hybrid rotation of the spindle swing and the workbench during the processing of the part. Therefore, the dynamic accuracy requirement of the five-axis machine tool is high. For the multi-axis machine tool, due to the influence of the environmental temperature, the change of the machine tool temperature, vibration, collision, internal mechanical stress and the like, the deviation exists between the actual position precision and the theoretical position precision of the rotating center of the turntable or the swinging head of the multi-axis machine tool, and the deviation can cause the reduction of the workpiece processing precision and the out-of-tolerance of the product size.
