What Data for This Category Looks Like
Business data for metal cutting machining comes from product drawings and 3D models, CAPP/CAM systems, machine tool collection terminals, tool management systems, MES systems, and measurement and inspection tool data. Daily documents include process routes, operation cards, tool lists, CNC programs, first-piece inspection records, patrol inspection forms, and measuring tool calibration records. Data updates trigger with each work order, workpiece, sampling batch, or tool change. Fields include tool life (unit: hours), process dimension tolerance (unit: microns), spindle speed (unit: revolutions per minute), cutting fluid flow (unit: liters per minute), and other specialized parameters.
What Constraints These Characteristics Impose on Workflow Orchestration
Scattered data sources and diverse data types in metal cutting machining require workflows to support connection to multiple types of external system nodes. Data updates trigger with events such as work orders and tool changes. This requires workflows to bind real-time event triggering mechanisms to match business update rhythms. Documents come in multiple formats, including long-text CNC programs and structured operation cards. This requires workflows to adapt to multi-format content extraction. Specialized field units require variables in workflows to bind corresponding parameters. This prevents calculation errors caused by unit mismatches. Error consequences include workpiece scrapping and machine tool downtime. This requires workflows to configure failure handling links to quickly respond to anomalies. This configuration applies to FastGPT v4.17.0.
How to Set the Configuration
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Trigger Node | Triggered by work order creation/tool change events | Matches the update rhythm of work orders and tool changes in metal cutting machining |
variables | Bound to tool life, process dimension tolerance fields | Corresponds to the specialized fields and units of this category's documents |
| Content Chunk Length | 800–1200 characters | Adapts to the splitting needs of long documents such as CNC programs and operation cards |
| API Call Timeout | 600 seconds | Adapts to the response duration of external systems such as machine tool collection and MES |
| Knowledge Base Recall Limit | Top 8 entries | Matches the document volume scale of workshop patrol inspection forms and first-piece inspection records |
| Workflow Failure Handling | Trigger alerts and record logs | Corresponds to the rapid response required for error consequences |
Three Common Mistakes
- Phenomenon: No pending tasks are generated after the workflow runs, and the node status shows empty fields. Cause: No category-specific variables such as work order number and tool number are bound in
variables, resulting in failure to extract key pending task information. - Phenomenon: After the HTTP API returns long text, the node returns a "request timeout" status code. Cause: No content chunking parameters are configured, and the long text exceeds the single-send limit, triggering system restrictions.
- Phenomenon: The content extraction node calls a self-built model and returns "parameter format error". Cause: The tool call parameters corresponding to
nodeIdare not correctly configured in the workflow, causing the self-built model to fail to recognize the function call format.
How to Confirm the Configuration Is Correct
- Trigger a simulated work order creation event, check whether the workflow nodes execute in the preset order.
- Import a CNC program document, confirm that the content extraction node can correctly split and transfer segmented content.
- Call the self-built model to test the content extraction function, confirm that the returned results meet the preset format.
- Trigger a simulated tool change event, check whether
variablescan correctly bind fields such as tool life and change time.
