What the data for this category looks like
Business documents for the metal cutting machining category include process routes, operation cards, tool lists, CNC programs, first-piece inspection records, patrol inspection forms, and measuring tool calibration records. Data sources cover product drawings and 3D models, CAPP/CAM systems, machine tool collection terminals, tool management systems, MES systems, and measuring and inspection tool data.
Data updates trigger with work orders, single-piece machining, spot checks, or tool changes. Operation cards contain fields such as operation number, processing equipment, and cutting parameters. CNC programs include G-code and tool compensation parameters. Measuring tool calibration records mark calibration dates and error values.
What constraints do these characteristics impose during deployment and upgrade
Data sources for this category are scattered, and update frequency changes dynamically with production rhythm. Deployment must support permission configuration and incremental synchronization for multiple data sources.
Multiple types of documents include large-volume 3D models and CNC programs, which impose requirements on storage capacity and bandwidth. Structured fields such as cutting parameters and tool life parameters need to accurately match Q&A retrieval logic. Upgrades must be compatible with field mapping rules of the original knowledge base.
In a workshop intranet environment, external access must be restricted. Deployment configurations need to adapt to intranet domain names and permission division across multiple work teams.
How to set the configurations
These configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–150 connections | Adapts to database query demands for concurrent work orders across multiple workshops, prevents Q&A timeouts caused by exhausted connections |
STORAGE_S3_ENDPOINT | Intranet object storage address of the machining workshop | Stores large documents such as CNC programs and 3D models, reduces intranet transmission latency |
REDIS_URL | Intranet connection address of a local Redis instance, port 6379 | Caches contexts of high-frequency inspection Q&A and tool wear data, improves response speed |
FILE_TOKEN_KEY | Randomly generated 32-character string | Encrypts access tokens for stored CNC program files, prevents unauthorized access to production documents |
FE_DOMAIN | Intranet access domain name of the machining workshop | Restricts Q&A system access only to the workshop intranet, ensures production data security |
ROOT_KEY | Configured according to internal team permission rules of the enterprise | Divides management permissions for workshop operation, quality inspection, and production teams, adapts to multi-role usage scenarios |
Three common errors
- Phenomenon: The team management function entry cannot be displayed in the management interface. Cause:
ROOT_KEYis not configured correctly, orFE_DOMAINdoes not point to the workshop intranet address, causing the permission module to fail to load. - Phenomenon: Knowledge base data is inconsistent after multi-node deployment. Cause:
MONGODB_URIandREDIS_URLare not configured uniformly, and the shared storage directory is not mounted to synchronize large files such as CNC programs, resulting in data desynchronization between nodes. - Phenomenon: The markdown format of Q&A results generated from the same text is abnormal. Cause: Adapted parsing rules are not configured for structured documents such as CNC programs and process routes, leading to incorrect identification of first- and second-level headings, and corresponding deviations in process hierarchy retrieval in production scenarios.
How to confirm that configurations are properly set
- Log in to the management interface via the workshop intranet, confirm that the team management module loads normally, and that teams can be created and corresponding permissions assigned.
- Upload a CNC program document, verify that the file can be parsed normally after upload and associated with the knowledge base index for inspection Q&A.
- Start two independent node instances, verify that CNC program files in the shared storage can be accessed simultaneously by both nodes without permission errors.
- Initiate an inspection Q&A related to tool wear, verify that the response time meets expectations and that the results include correct process parameters.
