Errors Correction of Cantilever CMMJin Feixiang, Chen Xiaohuai, Yang Hongtao et alJin Feixiang, Chen Xiaohuai, Yang Hongtao et alAbstract:The error structure of cantilever CMM which measures mold shell of steel bar is analyzed. And the model for distortion error of crossbearn which is be primary error resource is calculated. An error body modeling for the CMM is raised and errors correction is to be established by the model. Experiment proves that the body model for error can reduce and correct the measuring error of the CMM.[著者文摘]
