Abstract: The structure features and driving models of virtual-axis NC
machine tools are studied. According to different application
requirements, the three-axis control method, the five-axis
control method and the six-freedom control method are put
forward. These results lay a foundation for the product development of the virtual-axis NC machine tools.
Key words: Virtual-axis
