What This Category of Data Looks Like
Data sources for this category include product drawings and 3D models, CAPP/CAM systems, machine tool collection data, tool management systems, MES systems, and measurement and inspection tool data. Daily maintained documents cover 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, each workpiece, sampling batch, or tool change. Document fields include process datum, clamping scheme, tool model, dimensional tolerances, CNC program number, and other items. Units include millimeters, minutes, and others.
What Constraints Do These Characteristics Impose on the "Workflow Orchestration" Link
Data for this category is multi-source, scattered, and updated frequently. Workflows must support batch access and incremental synchronization of multiple data sources. This prevents retrieval of expired tool lists or CNC programs. Different document types have large differences in field logic. Exclusive search matching rules must be configured for process routes and CNC programs separately. This ensures returned content matches the datum and clamping scheme of the current work order. High-risk error outcomes require pre-validation steps to be embedded in workflows. Consistency checks must be performed on dimensional tolerances and tool life data from retrieved operation cards. This prevents abnormal parameters from entering subsequent links.
How to Set the Configuration
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Variable Binding | Associate variables with the workpiece model and operation number of the current work order | Narrow the retrieval scope to match the work order-specific scenario of metal cutting machining |
| Single Search Limit | Top 6 entries | Cover core information of multiple types of documents including process routes and operation cards, avoid redundancy |
| Context Window | 1000–1400 characters | Adapt to the text length of operation cards and CNC programs, avoid truncating critical parameters |
| Trigger Rule | Trigger by work order creation event | Match the update frequency of each work order, ensure data timeliness |
| Node ID Configuration | Bind nodeId as the unique identifier of each operation | Accurately locate the process specification and technical standard corresponding to the target operation |
| Validation Threshold | Calibrate based on actual measurements | Adapt to tolerance and tool life requirements for different workpieces |
Three Common Mistakes
- Phenomenon: After configuring variable binding, no optional values appear in the reference variable dropdown box of the knowledge base search. Cause: The workpiece model and operation number of the current work order are not correctly mounted to the
variablesparameter, so the system cannot recognize available variables. - Phenomenon: A timeout error with status code 504 is returned after the workflow is invoked. Cause: The single search limit is not set, and too many expired tool management and machine tool collection data are retrieved, exceeding the system response threshold.
- Phenomenon: The retrieved CNC program does not match the current operation, and a tool model mismatch occurs. Cause:
nodeIdis not bound to the current operation node, leading to cross-operation matching of unrelated CNC program documents.
How to Confirm the Configuration Is Complete
- Manually trigger a test work order, check whether the
variablesparameter carries the workpiece model and operation number information of the current work order. - Open the knowledge base search configuration interface, view the reference variable dropdown box, and confirm that the bound work order-related variables exist.
- Run the test workflow, verify that the retrieval results include documents such as the process route and tool list corresponding to the current operation.
- View the output logs of the validation link, confirm that the matching results of dimensional tolerances and tool life data meet expectations.
