3. standard architecture and content

(I) architecture

the high quality standard system of industrial mother machine is formed based on the mapping relationship between the industrial chain and the standard. Industrial mother machine industry chain refers to the reduction of material manufacturing equipment, such as material manufacturing equipment, additive manufacturing equipment as the core, from raw materials to end product manufacturing and application of each link of the complete chain, the upstream of the industrial chain covers supporting materials, parts, functional components and other supporting products, the downstream covers aerospace, rail transportation and other applications. The industrial chain of industrial mother machines is shown in Figure 1.

Figure 1 Industrial mother machine industry chain

the high-quality standard system of industrial mother machines is a technical standard group that supports the high-quality development of industrial mother machines. Through the mapping of standards with the upper, middle and lower reaches of the industrial chain, the "soft connection" between relevant standards and technologies, products and services is realized ". Among them, the basic general standard runs through the industrial chain of industrial mother machines and is the base of the standard system. The design of supporting standards constitutes the supporting guarantee for the production of industrial mother machines. Manufacturing equipment standards are the core of the standard system and reflect the overall technical level of industrial mother machines. Manufacturing process standards are the key to product molding and affect product quality and cost control. Inspection and testing standards are the basis for evaluating product quality; industry application standards provide technical support for industrial mother machines to empower other industries. The standard architectural relationships are shown in Figure 2.
