ABSTRACT
Evaluation of quality problems within mills has always been a dif cult undertaking. Quality engineers rely heavily on inspectors to locate defects and report them accurately. When defects are reported, the product is often diverted to reinspect/ rewind lines where quality personnel verify the defects and make disposition on the coil. The process of rewinding and checking is time-consuming, causing delays and adding signi cant costs. Quality problems that are reported back by customers are even more dif cult and often impossible to research and resolve.
