Abstract: Machining the cold roller blank is typically a multistage and multivariable quality control process, of which the quality of some key stages requires highly strict control. Taking the cold roller blanks supplied from a certain steel plant as example, the main stages of their machining procedure are described and analyzed showing the necessity of quality control of key stages which are determined by the simply improved Taguchi's quality loss function. Moreover, the MPCI is analyzed and computed, and the rationality and effectiveness of this method is verified through exemplification.
