Recently, Franco Anzani of SixSigmaIn Team and Marco Manara of Casappa S.p.A. worked together on a Six Sigma tolerance analysis project where they used Palisade Corporation’s @RISK 5.0. The model represents a tolerance analysis study performed to solve a potential assembly issue in a gear pump typically used in forklifts and low noise emission machines.

The model simulates the potential gap distribution in the pump and predicts the potential percentage of scraps, depending on both the nominal value and the variation (due to the machining capability) of the parameters.

@RISK 5.0 has been used to find the optimal combination of nominal design values and process variation to minimize the scrap percentage.

A combined optimization of the two responses has been performed, and an advanced 3D view of the simulated data has been added.
