Abstract

Our interest in multivariate capability indices (MPCI) is based on a case from a thermal spray­ing process at Volvo Aero Corporation, Sweden, where they wanted to determine the process capability of a three-dimensional variable. The process can be characterized as a high temperature “spray paint­ing” to protect the sprayed surface against, e.g. heat, corrosion and erosion. Different porosity is desirable depending on what the thermally sprayed coating should protect against. There is a relation be­tween the porosity and the in-flame variables and it would be preferable to se­cure the porosity during spraying instead as of today, afterwards. Since the three-dimensional, in-flame, variables are correlated one way to do this could be to calculate a MPCI of the in-flame variables. There are a number of different MPCIs described in the literature, but for only a hand­ful of these confidence intervals have been derived. In practise the conclusion about process capability must be drawn from a random sample. Hence, confidence or tests for MPCIs are important. Four different available methods for calcu­lating confidence intervals of MPCIs are being reviewed and compared. Current investigation shows issues that need to be solved before the studied methods can be applied more generally in practice.
