Five-axis linkage refers to the basic linear axis three axes X, Y, Z of the machine tool and two of the additional rotary axes A, B, C. The five axes move at the same time, and the posture of the tool or workpiece can be adjusted arbitrarily to achieve complex space Surface processing. The absolute number of machine tool axes is not a standard to measure the advanced level of CNC machine tools. The focus is on the number of linked axes. The five-axis linkage that the issuer can achieve is the current maximum linkage axis number of CNC machine tools.

2.3 Policy supervision

The supervision of the machinery industry is mainly carried out by the Ministry of Industry and Information Technology of the People’s Republic of China (Ministry of Industry and Information Technology) and the National Development and Reform Commission (NDRC) of the People’s Republic of China as the macro-management department. Functions of management.

The Ministry of Industry and Information Technology is responsible for the macro management of the industry: formulating and organizing the implementation of industry plans, plans and industrial policies, proposing policy recommendations for optimizing industrial layout and structure, drafting relevant draft laws and regulations, formulating regulations, formulating industry technical specifications and standards and organizing their implementation , To guide the quality management of the industry, assume the responsibility of revitalizing the equipment manufacturing industry’s organization and coordination, organize the formulation of major technological equipment development and independent innovation plans and policies, rely on the construction of key national projects to coordinate the implementation of relevant major special projects, promote the localization of major technological equipment, and guide The digestion and innovation of the introduction of major technical equipment.

The Ministry of Science and Technology is responsible for taking the lead in formulating science and technology development plans, guidelines and policies, drafting relevant draft laws and regulations, coordinating technical research, and organizing program demonstration, comprehensive balance, evaluation and acceptance in the implementation of major science and technology projects with relevant departments. The General Administration of Quality Supervision, Inspection and Quarantine is responsible for the formulation of technical standards and quality certification.

The China General Machinery Industry Association, a subsidiary of China Machinery Industry Federation, undertakes the self-discipline management responsibilities of various sub-industries. There are also the Logistics Equipment Professional Committee of China Federation of Logistics and Purchasing, China Federation of Logistics and Purchasing Rebar Processing and Distribution Technical Working Committee, China Federation of Logistics and Purchasing Steel Logistics Professional Committee, China Steel Structure Association Rebar Welded Mesh Branch, China Construction Enterprise Management Association etc.

In January 2012, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Finance and the State-owned Assets Supervision and Administration Commission of the State Council jointly issued the "Guiding Catalogue for Independent Innovation of Major Technical Equipment (2012 Edition)".

In March 2016, the "Outline of the Thirteenth Five-Year Plan for National Economic and Social Development" put forward the main indicators of economic and social development during the "13th Five-Year Plan" period, including the development of high-end equipment innovation projects, major energy development projects, and key transportation construction projects.

In August 2018, the "Guidelines for the Construction of National Intelligent Manufacturing Standard System (2018)" Ministry of Industry and Information Technology and the National Standardization Management Committee pointed out that standards should give full play to the guiding, standardizing, leading and guaranteeing role of standards in promoting the healthy and orderly development of the intelligent manufacturing industry.
