Quality Monitoring of Geometric Tolerances: a Comparison Study

While in the previous chapters different approaches for quality monitoring of geometric tolerances were discussed, in the present one a comparison study is provided in which all of these approaches are considered. The aim is to allow practitioners to select a specific method in a given situation. A manufacturing reference case study is first detailed, namely, profiles measured on machined items subject to geometric specification (roundness). Then, two simulation scenarios are considered for the comparison study, where each scenario is obtained by perturbing the real case study. Competing approaches are ranked in each production scenario considering as a performance index the quickness in detecting out-of-control shapes
