End of Engineering (EOE) Standards

📄 Document ID: MCM-ENG-EOE-2024 🔄 Revised: Oct 15, 2024 ● Approved

1. EOE Overview & Purpose

The End of Engineering (EOE) milestone marks the formal transition from design development to full-scale manufacturing. At MetalCore, EOE ensures that all engineering artifacts, material specifications, process parameters, and quality standards are validated, version-controlled, and ready for production release.

Once EOE is achieved, the design is frozen. Any subsequent modifications must follow the formal Engineering Change Notice (ECN) workflow to maintain traceability and compliance.

⚠️ Important Note No EOE release shall be authorized without completed First Article Inspection (FAI) reports and approved PPAP documentation where applicable. Production runs initiated prior to EOE sign-off are classified as pilot/tooling trials only.

2. EOE Documentation Checklist

All items below must be reviewed, approved, and archived in the PLM system before EOE sign-off. Use the checkboxes to track completion status.

✓ Document / Artifact Owner Required Format
3D CAD Models (Native & STEP) Design Eng. STEP 214 / JT
2D GD&T Drawings Design Eng. PDF-A / DXF
Bill of Materials (BOM) Product Eng. Excel / ERP Export
Material Certifications Supply Chain Mill Certs / MTRs
Process Flow & PFMEA Manufacturing Eng. PDF / Minitab
Control Plan & Inspection Specs Quality Eng. PDF / CMM Program
First Article Report (FAI) Quality Eng. AS9102 / ISO Format
Tooling & Fixture Specs Tooling Eng. 2D/3D Drawings

3. Quality & Compliance Standards

All EOE releases must align with the following regulatory and industry frameworks applicable to the product family:

  • ISO 9001:2015 – Quality Management Systems
  • AS9100D – Aerospace Quality Management (where applicable)
  • IATF 16949 – Automotive Production & Part Quality
  • ISO 13485 – Medical Devices (where applicable)
  • GD&T (ASME Y14.5-2018) – Dimensioning & Tolerancing Standards

Revision control must follow the A/B/C or 01/02/03 convention. Minor documentation updates that do not affect geometry or process parameters shall be tracked under Document Change Notices (DCN), not ECNs.

4. Production Handoff Protocol

  1. Pre-EOE Review Meeting – Cross-functional alignment between Engineering, Manufacturing, Quality, and Supply Chain.
  2. Digital Archive Upload – All approved documents uploaded to PLM with metadata tagging (part number, revision, effective date).
  3. Pilot Run Validation – Minimum 50-piece trial run with in-process and final inspection data collection.
  4. Capability Analysis – Cp/Cpk ≥ 1.33 for critical dimensions; ≥ 1.67 for safety-critical features.
  5. EOE Sign-Off – Electronic signatures from Engineering Manager, Quality Manager, and Production Supervisor.
  6. System Release – Part status updated to "Released for Production" in ERP/PLM. BOM and routing activated.
