We propose a method to carry out both tests through a common set of geometric parameters of the fixture configuration...

...R. Ascione; W. Polini; Q. Semeraro Many well-known approaches exist in the literature for tolerance analysis. All the methods proposed in the literature consider the dimensional and the geometric tolerances applied to some critical points (contact points among profiles belonging to couples of parts...
