Sheet Metal Cutting and Bending: Bid Document and Quotation Preparation: HTTP Interfaces and External Systems

Core data for sheet metal cutting and bending manufacturers comes from CAD/CAM software, order BOMs, sheet inventory systems, laser cutters, bending

What Data Looks Like for This Category

Core data for sheet metal cutting and bending manufacturers comes from CAD/CAM software, order BOMs, sheet inventory systems, laser cutters, bending machines, and MES systems. Daily produced documents include workpiece unfolding drawings, CNC cutting programs, bending process cards, nesting diagrams, first-piece records, and process flow cards. Data updates are triggered by order creation, daily inventory checks, and production changeovers. Fields include sheet thickness, bending angle, hole position coordinates, cutting dimensions, and workpiece numbers. Common units are millimeters, degrees, and square meters.

What Constraints Do These Characteristics Impose on HTTP Interfaces and External Systems

The need to access multiple data sources requires interfaces to pull corresponding data from different systems, and requires unified parameter identifiers to associate order and workpiece information. Business data with different update frequencies requires interfaces to support both on-demand triggering and scheduled pulling modes. The multi-variety, small-batch characteristics of sheet metal workpieces require that the number of workpieces per single request not be too large, to avoid interface overload. At the same time, the requirement for unit consistency of data fields requires interfaces to perform format checks on incoming drawing and inventory data, to prevent cutting errors and sheet waste caused by unit mismatches.

How to Configure Settings

Configuration ItemRecommended SettingRationale
Interface timeout duration600 secondsUnfolding and nesting calculations for sheet metal cutting and bending take a long time, so sufficient response time must be reserved to comply with the interface call specifications of FastGPT v4.17.0
Authorization verification configurationCarry a Bearer token in the Authorization headerComplies with general industrial API security specifications and adapts to access requirements for multiple external systems
Request parameter encapsulationCarry business data in the variables fieldUnifies the parameter structure, making it easier for external systems to parse sheet, process, and drawing information required for bidding
Response data return ruleReturn the full responseData fieldFacilitates external systems to verify the completeness and accuracy of quotation data
Maximum workpieces per single requestNo more than 20 workpiecesMatches the multi-variety, small-batch business characteristics of sheet metal work, avoiding interface overload
Trigger timing configurationTrigger after order submissionAligns with the node sequence of the manufacturer's bidding process, reducing invalid call times

Three Common Misconfigurations

  • Empty bending coefficient fields in interface responses lead to incorrect cutting dimension calculations for bid quotations. The cause is failure to carry the workpiece material and thickness information in the request parameters, which prevents the pulling logic for corresponding bending compensation data from being triggered.
  • Interface calls return a 504 timeout status code, making it impossible to generate complete bid documents. The cause is failure to configure a sufficiently long timeout duration, as the time required for sheet metal nesting and unfolding calculations exceeds the default interface time limit.
  • Submitted nesting diagram data cannot be parsed, resulting in missing cutting lists in bid documents. The cause is failure to encapsulate the variables field according to the agreed parameter rules, preventing external systems from associating corresponding drawing information.

How to Verify Configurations

  • Call a mock test interface with workpiece information from a real order, check whether the returned responseData includes complete cutting dimensions, bending angles, and sheet usage fields.
  • Configure the interface trigger timing to after order submission, and check whether the interface automatically initiates a request after order creation via the external system's call logs.
  • Simulate a scenario with an invalid token, confirm that the interface returns a 401 status code to verify that the Authorization verification configuration is effective.
  • Adjust the number of workpieces per single request, check whether the interface returns a parameter error prompt when the upper limit is exceeded, to verify that the maximum workpieces per single request configuration is effective.
