Abstract

An advanced software implemented method to support an inspector’s decision about a coil after each processing step to determine the coils future, ship or block, process, repair or re-route. For the first time, the full spectrum of gauge data from surface inspection to online roughness can be exploited to generate intelligent quality decisions. This paper presents a software approach, pioneered in 2005 in three installations to model grading decisions with rules from databases, to incorporate data from all available gauges with results on a single operator screen. The inspector does no longer take care for the obvious decisions, because the machine grading takes that part and at the same time provides to-the-point information for the non- obvious decision process. The unique aspects of this approach are the advanced data integration methods and software decision capabilities based on the parsytec 5i technology. For the first time, not only rejects, but also re-route and re-assignment decisions are possible through the integration of customer quality specification data and the access of order databases online. As a result, reduced internal rejects and a significantly improved re-assignment rate of non-prime coils to other orders have been observed.
