Abstract:In the measurement of freeform surfaces, the trace surface of the center of the probe is fitted by the use of bicubic parameter B spline and the least square method. And the measured surface is reconstructed through the 3 dimensional compensation of the probe. There is no requirement for the ordering of sampling points and determining of tangential vector and torsional vector of the measured surface on the boundary. The freeform surface is reconstructed with high precision. The method in this paper is applicable to the measurement and reconstruction of freeform surface precisely on 3 dimensional coordinates measuring machines.
Keywords:Freeform surface  Measurement  Probe compensation  Surface reconstruction  Bicubic parameter B  spline  3  dimensional coordinates measuring machines
