摘要：
Test specimen usually applied on checking dynamic precision of machine tools, but the performances of machine tools based on specimen cutting are still indeterminate. The modelings of four common test specimens for five-axis CNC machine tools are analyzed firstly. Then some important geometric features including the curvature, open-close angle, twisted angle of each specimen are studied. Next, the sudden change positions of acceleration on each axis are obtained during processing. So the various geometric characteristics are the key to test function of specimens. Finally, the superiority of Chinese "S" specimen is verified by the cutting experiments. The analysis results can be used to set up the relationship between test specimen and machine's dynamic performance, and contributed to the machine's error identification and traceability. © 2017 Journal of Mechanical Engineering.
