Cutting methods to evaluate accuracy of the virtual_axes CNC machine tool (VCMT) is tried to find out. In this paper, the testing standard for the conventional NC machine tools are analyzed. Based on the differences between the VCMT and the conventional machine tools, the measures for evaluation of accuracy at unaltered pose position of the VCMT is drawn out, and the suggestion for accuracy test at variational pose position is made.
