What the Data for This Category Looks Like
Core data for this category comes from CAD/CAM software, order BOMs, sheet inventory systems, laser cutter and bending machine equipment logs, and MES production systems. Daily output documents include unfolding drawings, CNC cutting programs, bending process cards, nesting diagrams, first-piece records, and process flow cards. Data updates are triggered by order creation, daily inventory checks, and each production changeover. Fields include bending coefficient, sheet specification, cutting size, bending angle, and other parameters, with units adjusted flexibly based on production scenarios.
Constraints for HTTP Interfaces and External Systems
The multi-variety, small-batch production model of this category requires interfaces to adapt to high-frequency dynamic requests and support differentiated parameter passing for different orders. Multiple data sources require interfaces to be compatible with different system data formats to enable cross-system synchronization of CAD programs, process cards, and equipment logs. The frequent update rhythm requires interfaces to be configured with reasonable timeout and retry mechanisms to avoid data synchronization failures caused by production interruptions. Additionally, since parameter errors can lead to waste of an entire sheet, interfaces must add data validation links to ensure that incoming parameters such as bending coefficients and cutting sizes meet production requirements.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer ${custom docking key} | Complies with the industrial API security authentication specification for FastGPT v4.17.0, preventing unauthorized access |
variables | {"orderNo": "", "sheetSpec": "", "bendCoeff": ""} | Matches the core production parameters for sheet metal cutting and bending, enabling dynamic adaptation to process requirements for different orders |
responseData | Return only process-matching content and equipment inspection logs | Filters irrelevant data, compresses interface response payloads, and improves call efficiency |
| Single search limit | Top 6 entries | The number of process documents associated with a single production batch for this category is moderate; too many entries will increase retrieval time |
| Maximum context | 1000–1400 characters | Matches the core content length range of bending process cards and unfolding drawings, avoiding context overflow |
| Timeout period | 240 seconds | Adapts to the typical time required for CNC cutting program parsing and nesting calculations, calibrated based on actual measurements |
Three Common Misconfigurations
- Phenomenon: Some production-related questions can match knowledge base results in the debug page, but no matching content is returned via API calls. Cause: The API request does not carry the same knowledge base authorization parameters as the debug page, or the order variables associated with the context are not correctly configured.
- Phenomenon: The b.md file uploaded to the dir1 directory in the API knowledge base is displayed as an upper-level directory file in the interface. Cause: The
responseDatareturned by the interface does not correctly pass the nested structure of directory levels, causing abnormal knowledge base parsing paths. - Phenomenon: SSL connection errors or authentication failure errors occur when calling the interface. Cause: The SSL certificate file is not correctly mounted in compose.yml, or a valid
Authorizationauthentication parameter is not set.
How to Verify Successful Configuration
- Send a test request carrying the
variablesparameter, and check if the returnedresponseDataincludes the bending process content corresponding to the current order. - View the knowledge base directory structure to confirm that files uploaded to the dir1 directory display the correct path with no level misalignment.
- Call the interface with an incorrect
Authorizationparameter, verify that an authentication failure prompt is returned, confirming that the security configuration is active. - Simulate a parameter change after a production changeover, send a new request, and confirm that the interface can dynamically adapt to the new
variablesparameter.
