Three-stage evolution from manual testing to SPC charts to physics-based prediction in green sand quality management

SPC was built for stable processes. Green sand is anything but stable. Every property is autocorrelated across time, cross-correlated with other properties, and driven by underlying physics that control charts cannot represent.
