Abstract: To improve the efficiency and success rate of Color-Material-Finishing (CMF) innovative design on products for solving the defects existing in current CMF innovative design such as low efficiency in acquiring design knowledge,imperfect knowledge management system and weak consistency between product and design.Based on the users' perceptual demands,the concept of Digital Twin was introduced,and a targeted industrial product CMF design service model framework based on the digital twin data model was constructed by drawing on the theory and method of five-dimension digital twin model.From the perspective of knowledge push,the organization structure and dynamics of product CMF semantic library could be understood on the basis of data cluster recombination theory,and the image scheme and optimal scheme combination in product CMF semantic library could be identified and predicted,which was used as extracted knowledge for designers to plan and design activities.Taking CMF creative design of VR glasses as an example,an intelligent CMF design engine was developed based on the product semantic theory,and the extracted knowledge was used to simplify the design complexity and optimize the design scheme,thus the auxiliary function of CMF design service model of industrial products driven by digital twins was verified effectively to the design.
