What the data for this category looks like
Business data sources for metal cutting machining include product drawings and 3D models, CAPP/CAM systems, machine tool collection data, tool management systems, MES systems, and measurement and inspection tool calibration records. Data updates are triggered by processing work orders, workpiece batches, sampling inspection links, and tool changes. Daily documents include process routes, operation cards, tool lists, CNC programs, first-piece inspection records, patrol inspection forms, and measurement tool calibration records. Fields include process parameters such as tool life (unit: hours), process spindle speed (unit: revolutions per minute), feed rate (unit: millimeters per revolution).
What constraints these characteristics impose on multi-turn dialogue and prompt engineering
Because data is dynamically updated with work orders and includes exclusive process parameters, multi-turn dialogue must bind the unique identifier of the current work order to avoid confusing tool lists and process routes for different workpieces. Document types are diverse and field unit requirements are strict. Prompts must explicitly call exclusive data such as CNC programs and first-piece inspection records for the corresponding process, and cannot rely on generic knowledge bases. Multi-turn interaction must limit the context scope to prevent redundant historical data from interfering with the current tender document and quotation preparation logic. Unified terminology standards for machining processes must also be maintained.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Bind the unique identifier of the current processing work order | Metal cutting machining data is dynamically updated with work orders, and must be associated with exclusive data such as process and tool information for the corresponding work order |
variables | Preset variables such as tool life, process spindle speed, feed rate | Quickly call standardized process parameters from operation cards and tool lists |
messages | Limit the context window to the first 10 turns of dialogue | Prevent redundant historical work order data from interfering with current document and quotation preparation |
| Maximum context | 800–1200 token | Match the typical length of metal cutting machining process parameters and documents |
| Question optimization | Enable | Optimize prompt wording to align with professional terminology standards for metal cutting machining |
Three common mistakes
- A 401 No auth credentials found error occurs. The cause is failure to correctly configure the API key for the current application, or the session permission associated with
chatIdhas not been fully bound. - Generated tender documents omit workpiece dimensional tolerance parameters. The cause is failure to preset tolerance fields from operation cards in
variables, which prevents prompts from calling the corresponding data. - Redundant historical work order content appears in dialogue results. The cause is failure to limit the context turns of
messages, which introduces historical data from unrelated processing batches.
How to confirm correct configuration
- Initiate a test dialogue, enter "Prepare the tender quotation and documents for the current workpiece", and check if the returned results include exclusive data such as the current work order's tool list and process route.
- View the session log to confirm that
chatIdis bound to the correct work order identifier, and no permission error messages are present. - Initiate 3 consecutive parameter adjustment requests, and check that the dialogue context retains valid history and no redundant non-current work order data.
- After enabling the question optimization function, check if the generated documents use professional standardized terminology for metal cutting machining.
