[0002] With the development of the economy, the number of complex parts such as steam turbine blades, gas turbine blades and various aircraft engine blades is increasing. In order to improve efficiency and reduce costs, better machine tools are needed to process workpieces quickly and efficiently. How to perform effective multi-axis processing on special-shaped parts is very important and urgent.

[0003] Modern machining requires increasingly higher processing accuracy, with precision requirements reaching micron level, such as steam turbine blades, gas turbine blades and various aircraft engine blades. This requires not only the control of the machining machine, but also the precise coordination of the machining tools and the bed to achieve the system accuracy requirements.

[0004] For machining complex surfaces such as steam turbine blades, gas turbine blades, and various aircraft engine blades, conventional 3D and 4D CNC machine tools struggle to meet these requirements.
