Data Profile for This Use Case
Business data for sheet metal cutting and bending scenarios typically comes from CAD/CAM software, order BOM systems, sheet material inventory ledgers, equipment logs from laser cutters and bending machines, and MES production management systems. Daily produced documents include unfolded drawings, CNC cutting programs, bending process cards, nesting diagrams, first-piece inspection records, and process transfer cards. These documents contain fields such as sheet material thickness, bending angle, hole position tolerance, and cutting dimensions, with units mostly being millimeters, square meters, and kilograms. Data update frequency is adjusted in real time based on orders, daily production changeovers, or equipment operation, with no fixed cycle.
Constraints for Multi-turn Dialogue and Prompts Workflows
Multi-source heterogeneous engineering documents and real-time updated business data require multi-turn dialogue to bind to the unique identifier of the current order, avoiding context confusion between different work orders. Precise engineering fields require prompts to specify the retrieval scope of the corresponding dataset, avoiding returns of irrelevant process data from other categories. The multi-variety, small-batch production model requires each dialogue round to focus on the current order’s drawings and work orders, excluding redundant data from other orders. The serious consequences of errors require gradual verification of key parameters such as bending coefficients and nesting plans during multi-turn dialogue, ensuring accuracy at each step.
Configuration Recommendations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum Context | 8000–10000 characters | Retain the dialogue history and core business parameters for the current order to avoid context overflow |
| Single Search Limit | Top 6 results | Focus on matching results for the current sheet metal cutting and bending scenario to reduce redundant data interference |
| variables | Bind the current order's sheet material inventory ID | Pass real-time business identifiers via the variables parameter to ensure access to the latest sheet material data |
| chatId | Bind the unique number of the current work order | Isolate dialogue contexts for different orders via the chatId parameter to avoid data confusion |
| Context Retention Rule | Retain the most recent 10 rounds of dialogue content in messages | Focus on the latest business parameters for the current order to avoid redundant historical data |
| File Upload Limit | Under 10 MB | Adapt to the size of engineering files for sheet metal cutting and bending scenarios to avoid upload timeouts |
Common Misconfigurations
- Issue: After upgrading to FastGPT v4.17.0, interface errors occur when uploading CNC cutting programs or nesting diagrams. The cause is that the file upload path configuration was not updated after migrating S3 storage.
- Issue: When retrieving the knowledge base during dialogue, a large amount of irrelevant process content is returned, and it is not possible to specify only searching for the exclusive dataset for sheet metal cutting and bending. The cause is that the unique identifier of the corresponding dataset was not bound in the prompt.
- Issue: Calculation deviations for bending coefficients or nesting plans repeatedly occur during multi-turn dialogue. The cause is that key business parameters for the current order were not retained in
messages, leading to loss of core context information.
How to Verify Proper Configuration
- Upload a sheet metal unfolded drawing, and verify whether the dialogue automatically associates the current order's BOM data and sheet material inventory information.
- Submit the query "Verify the parameters of the current bending process card", and confirm that the returned results only come from the bound exclusive sheet metal cutting and bending dataset.
- Initiate a multi-turn dialogue, modify the bending coefficient, and confirm that subsequent queries retain the latest parameter values.
- Upload a nesting diagram with a size of 5 MB, and confirm that the upload and parsing are completed normally.
