The aim of this research is to expand application areas of the advanced manufacturing concept and technology based on combining the traditional weaving techniques with digital forming technology. Through the man-machine interface of traditional weaving techniques of processing machines and craftsmanship complex data visualization and interactive operation, Virtual Reality Technology can realize computer model images, which is a kind of new form of artistic language and the key of VR art presenting its unique advantages. Combined with digital technology, the production of raw materials can generate 2D graphics, and 3D object can also be generated by using rapid solidification laser material preparation and forming technology (3-Dimension Printing). In one word, the traditional weaving techniques of processing machine and craftsmanship realized the complete inheritance. In this paper, main content are 4 parts including the analysis of ethnic traditional weaving technology in southwest areas of China, the usage of fashion digital simulation forming technology, the combination of traditional weaving technology with digital forming technology, and expanding of digital customized technology. We started our research work using grass linen and its weaving machine. In the end, the conclusion of study will be used to build the digital museum online for Southwest Ethnic Traditional Weaving Technology Museum, which is also bridging around world marketing for traditional culture.
