| Abstract: | The mechanical structure of a CNC gearing measurement center is introduced.Based on FEA（Finite Element Analysis） method,the model of the gearing measurement center is modeled for static analysis and modal analysis.The calculated results provided deformation of the machine caused by inertia during measuring.The modal analysis results show that the first natural frequency is much higher than the measurement frequency.This means that the static analysis results can be applied for calculation of measurement error.The calculation method and results is important for mechanical design of the gearing measurement center. |
