What Data Looks Like for This Category
Core data for this category covers 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 tool data terminals. Data updates trigger with each work order, each workpiece, sampling, or tool change. Fields include tool life (unit: minutes per piece), process dimension tolerance (unit: mm), and CNC program line numbers. Formats cover structured tables and unstructured code and documents.
Constraints for Workflow Orchestration Posed by These Characteristics
Multi-source heterogeneous data sources require workflows to support cross-system pull nodes, and adapt to the interface formats of different data sources separately. The high-frequency update feature requires workflows to support real-time triggering, to avoid data lag caused by scheduled pulling. Diverse document types require workflows to embed multi-format parsing nodes, to handle structured operation cards and unstructured CNC programs separately. Abnormalities such as tool wear and dimension drift need real-time verification, requiring workflows to embed rule trigger nodes, and immediately start an abnormal processing flow when an abnormality occurs. Datum conversion and clamping scheme selection depend on previous process data, requiring data flow between workflow nodes to strictly follow the process route sequence.
How to Set the Configuration
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow trigger method | Triggered by work order submission event | Matches the rhythm of data updates tied to each work order for this category |
| Multi-source data pull node timeout | 600 seconds | Covers the conventional return delay range of machine tool collection and tool management systems |
variables binding rule | Bind the core work order fields of the data source corresponding to nodeId | Ensure workflow nodes can directly call business data such as work orders and tool lists |
| Abnormal verification node trigger condition | Trigger when the process dimension deviation exceeds 0.02mm or the remaining tool life is lower than 10%, calibrated by actual measurement | Matches the process tolerance and tool life threshold requirements of this category |
| Node execution retry count | 3 times | Addresses occasional network fluctuations during multi-source data pulling |
| Original file preview association configuration | Bind the original document storage path | Support online preview of the original file before slicing |
Three Common Errors
- Phenomenon: The workflow stalls after reaching the multi-source data pull node, with a timeout status displayed. Cause: Timeout values are not set separately for different data sources such as machine tool collection and MES systems, and uniformly using an overly long timeout threshold causes blocking.
- Phenomenon: The tool list data bound to
variablesin the workflow is empty. Cause: The data source node corresponding tonodeIdfor the tool management system is not configured, causing the variable to fail to pull correctly. - Phenomenon: The original file preview details cannot be opened during workflow testing. Cause: Only the knowledge base slicing data is bound, and the association node for the original document storage path is not configured, making it impossible to point to the original document before slicing.
How to Confirm Proper Configuration
- Trigger a test work order, check whether the workflow automatically pulls business data such as the corresponding process route and tool list.
- Simulate scenarios of tool wear or dimensional deviation, confirm whether the abnormal verification node triggers the preset process.
- Check whether the fields bound to
variablesinclude core business parameters such as work order number and process dimension. - Click the original file preview node in the workflow, confirm that it can jump to the original document storage location.
