| Abstract: | Aimed at seven-axes comprehensive measurement of axisymmetric body,the methods of data fusion for three groups data measured by probes in cylindrical coordinate system are studied.The principle of measuring system is introduced,and the calibration methods for probe location in the direction of sensitive and non-sensitive are analyzed.The mathematical model of data fusion is established based on the calibration result.This measurement system evaluates all the geometric parameters of outer contour and inner contour during one measurement.The experiments show that the measuring uncertainty of the machines is less than 0.02 mm which meets the general requirement in most cases. |
