The invention discloses a digital twin-driven processing quality tracing and dynamic control method and system. The method comprises the steps that the analysis and effect quantification of influencefactors of processing quality is carried out through combining with a principal component and grey correlation analysis method; an association and integration mechanism of a processing quality information semantic description model supporting quality tracing and quality information is established, a manufacturing unit Internet of Things system oriented to processing quality dynamic control and a virtual and real information fusion twin database are constructed, and a processing quality dynamic control method based on a digital twin technology is adopted on the basis. Through real-time interaction of physical processing and virtual simulation, the method can efficiently and accurately trace back a fault source on the basis of on-site data acquisition; through dynamic simulation optimizationand quality prediction, p
