Introduction
Analysis of the core content of the standard
| Knowledge category | Core content | Coding characteristics |
|---|---|---|
| Basic process knowledge | Mechanical manufacturing theory, process standards and specifications, typical examples | Starting with 01-04, 4-digit category code |
| Process design knowledge | Scheme design, processing technology, assembly technology, etc. | Starting with 02, attribute code to distinguish knowledge forms |
| Process management knowledge | File management, equipment management, after-sales service | Starting with 03, extensible group code |
Technology Evolution Analysis
This standard innovatively adopts the flexible classification and coding system to break through the limitations of traditional fixed code positions:
- Main and auxiliary code structure: category code (4 fixed digits) + group code (2-16 digits expandable) + attribute code (ad)
- Dynamic expansion capability: the group code increases by two digits for each subdivision level to meet the needs of process knowledge iteration
- Multi-form compatibility: attribute codes are used to distinguish different carrier forms such as structured knowledge (a) and electronic documents (b)
Implementation Suggestions
Enterprise Application Path
- Knowledge Inventory Phase: Establish an enterprise process knowledge map with reference to Appendix A of the standard
- System docking stage: embed coding rules into the PLM system and MES system
- Dynamic maintenance mechanism: establish special coding for process intelligence (starting with 04) to track the development of new technologies
Typical application scenarios
Application case of an automotive parts company:
Use "020103a" to encode the welding process design program. The first two digits 02 represent process design knowledge, 01 represents process scheme design, 03 corresponds to design program, and a represents structured knowledge.
Interpretation of the value of the standard
This standard uses a scientific classification system to:
- Solve the problem of process knowledge islands in manufacturing enterprises
- Establish a foundation for the connection between process data and intelligent manufacturing systems
- Provide a standardized framework for the construction of process knowledge graphs
