Fixture fault diagnosis is a critical component of currently evolving techniques aimed at manufacturing variation reduction. The impact of sensor location on the effectiveness of fault-type discrimination in such diagnostic procedures is significant. This paper proposes a methodology for achieving optimal fault-type discrimination through an optimized configuration of defined 'sensor locales'. The optimization is presented in the context of autobody fixturing - a predominant cause of process variability in automobile assembly. The evaluation criteria is the ability to provide a consistency of best match, in a pattern recognition sense, of any existing fixture error to a classified, anticipated error set. The proposed analytical methodology is novel in addressing the design issue at both the fixture design and the sensor location planning levels - constituting a design for fault detectability. Examples of the locale planning and an application to an industrial fixture configuration are presented to illustrate the proposed methodology.
