JB/T5992.10 Classification and Code of Mechanical Manufacturing Process Methods Code other process methods
3 Basic principles of process method classification
3.1 Mechanical manufacturing process methods are divided into four levels: large category, medium category, small category and subdivision. If the four levels are not enough, you can Further refinement.
3.2 The name of the process method in each level must comply with the corresponding terminology standards. 3.3 Each level should leave a space for use when needed. 4 code structure
4.1 The codes of the process methods are all represented by Arabic numerals, among which the codes for large categories, medium categories and small categories are all expressed in 0~9- The subdivision code uses two digits from 01 to 99, as shown below. Ministry of Machinery and Electronics Industry approved on 1992-07-17 for implementation on 1993-07-01

4.3 The last code bit of each level is the containment code. 5 Principles of classification of major and medium categories of process methods 5.1 Major categories of process methods are divided according to process majors. 5.2 Medium categories of process methods are divided according to the process characteristics of each major category. 6 Names and codes of major categories and intermediate categories of process methods. The names and codes of categories and intermediate categories are as specified in the table. 7. The division and code of subcategories and subcategories of process methods. The division and codes of subcategories and subcategories of process methods are in accordance with the provisions of JB/T5992.25992.10, 2
