What the Data for This Category Looks Like
Data sources for metal cutting machining processes and standards include product drawings and 3D models, CAPP/CAM systems, machine tool collection data, tool management systems, MES, and inspection and measuring tool records. Data updates trigger with processing work orders, individual workpieces, sampling inspection links, or tool changes. Daily documents cover process routes, operation cards, tool lists, CNC programs, first-piece inspection records, patrol inspection forms, and measuring tool calibration records. These documents include fields such as process tolerances (unit: mm), tool life (unit: hours), CNC program segment numbers, and clamping reference positions.
Constraints on Multi-turn Dialogue and Prompt Engineering Workflows
Data sources are scattered and updates occur frequently. Dialogue systems must accurately bind exclusive parameters for the current work order to avoid mixing data across work orders. Documents contain structured content such as CNC program code and process parameters with units. Multi-turn dialogue must retain context parameters to ensure subsequent questions can link to previously mentioned process and tool information. Long documents include both title-based explanations and code snippets. Relying solely on title segmentation splits CNC program blocks, leading to incomplete retrieval matches. Process problems often involve dynamically changing scenarios such as datum conversion and tool wear. Gradual clarification of the current machining status is required through multi-turn dialogue.
Configuration Settings
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Chunk Separator | #, ## combined with CNC program segment numbers (format: Oxxxx) | Adapt to long documents containing CNC programs, avoid splitting the association between code blocks and process explanations |
variables binding fields | Work order number, tool model, operation number | Accurately match exclusive process data for the current machining work order, narrow retrieval scope |
messages historical context length | Top 10 conversation turns | Balance completeness of context information and system response speed, avoid overload |
| Single retrieval recall count | Top 6 entries | Focus on core process documents, reduce interference from irrelevant entries on dialogue logic |
chatId persistence setting | Enabled | Bind the full-process dialogue of the current machining work order, avoid repeated confirmation of basic parameters |
Three Common Misconfigurations
- Symptom: CNC program fragments are missing from search results when using pure
#/##title separators to split long process documents. Cause: Metal cutting process documents contain CNC program code blocks. Using only title splits breaks the association between code and process explanations, leading to incomplete retrieval matches. - Symptom: The conversation module returns a 422 status code when called. Cause: The
variablesfield is not correctly bound, resulting in missing retrieval parameters and inability to match process documents for the corresponding work order. - Symptom: Conversation records disappear after the dialogue window is refreshed, but background conversation records are still visible. Cause: The
chatIdpersistence configuration is not enabled. Sessions are only stored in front-end temporary cache and not bound to back-end session identifiers.
How to Verify Correct Configuration
- Upload a long process document containing CNC programs, initiate a retrieval request that includes a program segment number, and check if the corresponding code fragment is returned completely to confirm the chunk separator configuration is reasonable.
- Initiate a multi-turn dialogue that includes a work order number and tool model, check if
variablescorrectly bind the corresponding fields, and verify that subsequent questions can link to previously mentioned process parameters. - Close and reopen the dialogue window, check if the
chatIdpersistence configuration is active and that conversation records are fully retained. - Initiate a multi-turn dialogue of unconventional length, check if the
messagescontext length configuration adapts to the current business scenario, with no obvious context overflow or response delay issues. - Check that the dialogue output switch can be configured to hide non-essential system prompts or intermediate step content as needed.
