What This Category of Data Looks Like
This category of data covers full production process documents for machine tool factories, precision component factories, and machining workshops of equipment enterprises. Documents include process routes, operation cards, tool lists, CNC programs, first-piece inspection records, patrol inspection forms, and measuring tool calibration records. Data sources include 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 are triggered by work orders, single-piece production, sampling inspections, or tool changes. Individual documents contain fields such as process number, tool model, cutting parameters, and dimensional tolerance values. Common units are millimeters, revolutions per minute, and millimeters per minute.
Constraints for HTTP Interfaces and External Systems
The multi-source heterogeneous data and high-frequency update characteristics of this category require HTTP interfaces to support receiving data in multiple formats: structured process parameters, unstructured CNC program text, and 3D model attachments. A single interface request must carry multiple types of documents associated with a single work order. Data volume increases with work order complexity, so interfaces must adapt to variable-length request bodies. Real-time data update requirements mean interfaces must support short-interval polling or event pushing. Field format consistency from different systems must be verified to avoid cross-review failures caused by differences in field naming between tool management systems and MES systems. Long text content of CNC programs must avoid interface truncation, so sufficient request body and response body size limits must be configured.
Configuration Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Obtained from the docking key management module of machine tool collection systems and MES systems, in the format Bearer {token} | Used to verify access permissions for external systems, complying with HTTP interface identity verification standards |
variables | Configured as {"baseURL": "https://your-factory-mes.com/api/v1", "toolDB": "https://your-tool-mgmt.com/api"} | Stores cross-system interface address variables to avoid increased maintenance costs caused by hardcoding |
responseData | Configured to only return {"pass": boolean, "error_fields": array} | Simplifies interface response content to adapt to cross-review result verification requirements |
| Request timeout | 30 seconds | Adapts to transmission duration of long texts such as CNC programs, avoiding request interruptions caused by large data volumes |
| Request body size limit | 1000 MB | Accommodates single work order document packages containing 3D model attachments |
| Retry count | 3 times | Addresses interface call failures caused by temporary fluctuations in machine tool collection systems |
Three Common Configuration Mistakes
- Symptom: Interface calls return a 401 unauthorized error, or requests are rejected by external systems. Cause: The
Authorizationparameter is not configured correctly, a valid access token is not obtained from the corresponding system, or the token format does not meet requirements. - Symptom: External document links referenced in generated cross-review reports lack the http:// prefix, preventing normal access. Cause: The protocol header is not fully completed in baseURL when configuring
variables, or resource paths returned by interfaces are not spliced with complete protocol prefixes. - Symptom: Interface calls trigger security alerts, or external systems block requests. Cause: HTTP interface TRACE request support is not disabled, creating risks that may be exploited by attackers.
How to Confirm Proper Configuration
- Call the configured HTTP interface, pass typical document data for a single work order, and check if the
responseDatafield in the interface return contains expected review results. - View interface call logs to confirm the
Authorizationparameter is correctly carried in the request header, with a format that meets the requirements of the external system. - Check if the interface addresses configured in
variablesare accessible normally, and verify connectivity by initiating test requests through tools. - Disable HTTP interface TRACE request support, and confirm that external systems no longer block calls to this interface.
