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 maintenance-related documents include process routes, operation cards, tool lists, CNC programs, first-piece inspection records, inspection sheets, and measuring tool calibration records. Data update frequency triggers include work orders, individual products, sampling batches, and tool changes. Data fields include machine tool number, tool wear amount, process dimension deviation, CNC program version number, and more. Units include millimeters, revolutions per minute, minutes, and other standard industrial units.
How These Characteristics Impact HTTP Interfaces and External Systems
Multiple heterogeneous data sources require interfaces to support different system field formats. Interfaces must pull tool wear data from tool management systems and work order information from MES systems. High-frequency data updates require interfaces to support incremental pulls or real-time synchronization. This avoids repeated transmission of full datasets. Large volume differences across document types such as CNC programs and process routes require interfaces to support large file chunked transmission. Severe consequences of business errors require interface authentication and timeout configurations to meet industrial system security and reliability requirements.
Configuration Settings
This document is written for FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {API key assigned by FastGPT platform} | Complies with security authentication specifications for industrial systems, avoids plaintext transmission of sensitive information |
variables | Bind business variables such as machine tool ID, tool number, work order number | Matches work order data for metal cutting machining, ensuring Q&A results align with current production scenarios |
responseData | Return inspection results, maintenance suggestions, associated process card ID, tool list ID | Aligns with business requirements for equipment inspection and maintenance, directly outputs actionable business information |
| Request timeout duration | 10–60 seconds | Adapts to loading times for documents such as CNC programs and process routes, avoids timeout triggers from large file transfers |
| Multi-file parameter configuration | Pass content in nested arrays within the messages array format | Supports simultaneous upload of multiple types of documents such as inspection sheets and measuring tool calibration records |
| Authentication refresh cycle | Calibrate based on actual measurements | Adapts to token expiration rules for internal enterprise systems, avoids authentication failures |
Three Common Configuration Mistakes
- Phenomenon: Interface requests time out after more than 1 minute, returning a 504 status code. Cause: The timeout configuration was not adjusted to match the loading duration of large documents like CNC programs and process routes for metal cutting machining. The general default threshold was used instead.
- Phenomenon: Maintenance suggestions returned by
responseDatado not match the tool information for the current work order, and fields are missing. Cause: Tool wear data collected by machine tools and operation card information were not injected into thevariablesvariable. This causes Q&A results to deviate from actual production scenarios. - Phenomenon: The interface reports an error during multi-file upload. Documents such as inspection sheets and measuring tool calibration records are not correctly identified. Cause: File information within the content array was not passed in the required nested format. This does not meet the interface's parameter specifications.
How to Confirm Proper Configuration
- Call the interface with a test work order ID. Check if the returned
responseDataincludes business fields such as associated process routes and tool lists. - Send a request without a valid
Authorizationheader. Confirm the interface returns a 401 Unauthorized status code to verify the authentication configuration works. - Upload multiple CNC program and inspection sheet files. Confirm the interface can correctly receive and parse all file contents.
- Send a simulated request lasting 50 seconds. Confirm the timeout configuration does not trigger exceptions, meeting the loading requirements for business documents.
