Fitting of the points to the nominal surface for a paraboloid A New Algorithm to Assess Revolute Surfaces 4. CONCLUSION 165 The present work shows an approach to assess profile tolerance related to revolute surfaces that is both general and easy to implement. The proposed approach is based on the new concepts under development by the ISO/TC213 Technical Committee. The approach transforms the measurement data through an opportune homogeneous transformation matrix in order to minimize the distance between the cloud of measured points and the reference element of the class of surfaces from which the sampling comes. The best transformation parameters are searched by fitting the set of p...
