Thermal Modal Analysis for Volumetric Error Characterization

Abstract The volumetric accuracy of machine tools is significantly impacted by thermal errors, making the evaluation a significant challenge for manufacturing industry. Several technical solutions have been implemented, both at industrial and research level, to address this issue. However, considering errors in error characterization adds complexity process remains an open topic field. In study, novel technique based on simulated Thermal Modal Analysis proposed three-axis tool. This approach involves analyzing impact modes tool's structural elements error, providing that incorporates physical meaning structure. will serve as foundation future experiments combine it with other techniques achieve comprehensive understanding errors.
