映射, 可拓分析, 产品质量, 过程质量, 质量特性

The mapping model between product quality and process quality was set up to illustrate the relationship among them firstly. Then the extension theory was introduced into extension definition of product quality, process quality and the mapping. And the theory and methods of quantitative metrics,extension analysis and priority calculation of the mapping between product quality and process quality were put forward. Finally, these methods were applied in mapping analysis of bearing quality, and the analysis results discover the relationships between the bearing quality and the grinding process characteristic parameters. This research is of great significance for quality planning, quality control, quality decision-making and quality improvement.
