Unformatted text preview: ther parameters” present in the set (7) are h and r. Varying randomly these parameters between two sets, differing just for a factor of scale, so that the similarity of the two surfaces is preserved, for every point sampled, it is possible to build datasets of points of known form tolerance. The resulting form error can be easily calculated and it is reported in Table1. The set of parametric equations, explicating equation (6) for a paraboloid, is: ⎧ u cosν ⎪x = a h ⎪ ⎪ u ⎪ sinν . (8) ⎨y = a h ⎪ ⎪z = u ⎪ ⎪ ⎩ A New Algorithm to Assess Revolute Surfaces 163 This is the parametric form of the paraboloid having radius a at height h. a and h are reported in Table 2 as max radius and height, respectively, see Figure 3. As well as for the truncated cone, paraboloid datasets are obtained varying the “other parameters” a and h, so that every sampled point is randomly extracted from two different perfect surfaces of known distance. The resulting form error can be easily calculated and it is reported in Table 2 as form er...
