Unformatted text preview: or decomposing the fitting operation in two sub-operations. The first operation is the fitting of the set of points to the higher order reference element of the datum, while the A New Algorithm to Assess Revolute Surfaces 159 second operation is the fitting of the set of points to the remaining reference element of the datum, under the constraint given by the first operation. Afterwards the individuation of the best-fit set of transformation parameters, the form tolerance of the inspected feature can be assessed following the tolerance definition supplied by the GD&T Y 14.5 standard. Numerical simulations were performed in order to validate the effectiveness and the robustness of the approach. The great advantage of this new algorithm is that its formulation may be applied to assess any kind of surfaces without any adaptation effort. In the following the problem proposed algorithm is mathematically described (§2) and applied to tolerance assessment of revolute surfaces (§3). Finally, the performances of the proposed algorithm are d...
