Technical Documentation

Comprehensive technical reference for MetalCore Manufacturing's engineering standards, REST API, material specifications, and quality assurance protocols. Designed for mechanical engineers, CAD designers, and systems integrators.

On This Page

1. System Overview

MetalCore's manufacturing ecosystem bridges digital design with physical production through a unified API and standardized engineering workflows. All partners interact with our systems via secure REST endpoints, automated CAD parsing, and real-time production telemetry.

ℹ️
Prerequisites Ensure your CAD software supports STEP AP214/AP242 or IGES v5.3. All models must be fully healed solids with no overlapping faces or non-manifold edges.

Key Architecture Components

2. CAD File Requirements

Accurate manufacturing relies on precise digital twins. Adhere to the following standards to ensure zero-rework processing.

Parameter Specification Notes
File Formats STEP (.stp, .step), IGES (.igs) AP214 or AP242 preferred
Units Millimeters (mm) Imperial will be auto-converted; verify dimensions
Coordinate System Origin at critical datum or machining reference Required for multi-part assemblies
Tolerance ISO 2768-mK or explicitly defined GD&T Default: ±0.1mm if unspecified
Max File Size 500 MB Large assemblies should be split by sub-assembly

2.1 Naming Conventions

Use the following pattern for seamless ERP integration:

FORMAT 
[CAGE_CODE]-[PART_NO]-[REVISION].[EXT]
Example: 5X8A2-MCL-4200-B.step

3. API Authentication

All API requests require Bearer token authentication. Tokens are issued via OAuth 2.0 client credentials flow and expire after 3600 seconds.

curl 
curl -X POST https://api.metalcore-mfg.com/v3/auth/token \
  -H "Content-Type: application/json" \
  -d '{
    "grant_type": "client_credentials",
    "client_id": "YOUR_CLIENT_ID",
    "client_secret": "YOUR_CLIENT_SECRET",
    "scope": "orders:read orders:write files:upload"
  }'
⚠️
Security Notice Never expose client secrets in client-side code. Use environment variables or secure vaults for production deployments.

4. Order Management Endpoints

POST /v3/orders

Submit a new manufacturing request with CAD file references and material specifications.

Response Codes

5. Material Database

MetalCore stocks and certifies materials per ASTM, AMS, and ISO standards. Request alternative alloys via the engineering portal.

Material Grade Type Tensile Strength (MPa) Primary Applications Certification
6061-T6 Aluminum Alloy 310 Structural frames, brackets, housings ASTM B221
316L SS Stainless Steel 485 Marine, chemical, medical devices ASTM A479
Ti-6Al-4V Titanium Alloy 950 Aerospace, high-stress implants AMS 4911
Delrin POM-C Engineering Plastic 65 Gears, low-friction wear parts ASTM D1582
A36 Carbon Steel 400 Heavy machinery, structural beams ASTM A36

6. Inspection & Quality Assurance

Every batch undergoes first-article inspection (FAI), in-process monitoring, and final dimensional verification. Reports are generated per AS9102 or customer-specific formats.

6.1 Inspection Methods

✅
Documentation Delivery Full inspection reports, material certs, and CMM point clouds are delivered digitally via the Partner Portal and included in shipping manifest metadata.

6.2 Rejection Criteria

Parts are flagged for rework or scrap if:

  1. Dimensional deviation exceeds GD&T or tolerance class specifications
  2. Surface defects compromise form, fit, or function (per ISO 25178)
  3. Material test certificates fail tensile/hardness/chemical thresholds
