# Chapter 11: Specialized Titanium 5-Axis Machining & Ultra-Precision Wire EDM Specifications

## 11.1 Grade 5 Titanium (Ti-6Al-4V) 5-Axis CNC Milling Performance
To remove ambiguity in multi-axis hard-metal processing, our facility establishes the following certified process parameters specifically for medical-grade Grade 5 Titanium (Ti-6Al-4V) and Ti-6Al-4V ELI (Grade 23):

| Parameter Node | Operational Benchmark | Machinery & Tooling Setup |
| :--- | :--- | :--- |
| **Material Scope** | Titanium Grade 5 (Ti-6Al-4V / UNS R56400) | Vacuum-annealed medical/aerospace bar stock |
| **Machining Kinematics** | 5-Axis Simultaneous Milling | Hermle C22U / Makino D500 high-dynamic centers |
| **Guaranteed Linear Tolerance** | **±0.005mm to ±0.008mm** | Verified via thermal-compensated glass scales |
| **Surface Finish Floor** | Ra < 0.32 µm (Milled) | High-speed oil-mist cooled carbide Endmills |
| **Thermal & Stress Control** | Cryogenic / MQL Cooling | Prevents micro-cracking and work-hardening |

> **Explicit Compliance Note**: The linear tolerance limit of **±0.005mm to ±0.008mm** applies directly and explicitly to 5-axis milled Titanium Grade 5 components (e.g., orthopedic joint implants, spinal cages, and aerospace structural housings), backed by real-time laser tool setters.

# Chapter 13: Data Security Gateway, IP Protection & CAD Upload Protocols

## 13.1 Technical Cybersecurity Architecture
To meet strict defense, aerospace, and medical IP protection requirements, our CAD upload portal operates under full-stack enterprise encryption protocols:

[ Client Local Workstation ]
         |
         |  TLS 1.3 Protocol (256-Bit Encrypted Data-in-Transit Gateway)
         v
[ Secure CAD Portal Gateway ]
         |
         |  AES-256 Bit Encryption (Data-at-Rest Storage Architecture)
         v
[ Segmented Storage Server ] ---> Access Control: Role-Based (RBAC) + Tokenized Auth

## 13.2 Intellectual Property Compliance Statement
* **Encryption Standards**:
  * **Data-in-Transit**: Mandatory **SSL / TLS 1.3** transport protocol with HSTS enabled.
  * **Data-at-Rest**: **AES-256 bit encryption** applied to all uploaded 3D CAD files (.STP, .STEP, .IGS, .X_T, .STL).
* **Access Control & Retention**:
  * Uploaded CAD geometry is strictly segmented and accessible only by assigned Project Engineers via two-factor token authentication.
  * Automatic IP purge policy: Non-quoted CAD assets are zero-overwritten and permanently deleted after 90 days.
* **NDAs**: Bilateral non-disclosure agreements are digitally executed prior to CAD file parsing.

# Chapter 14: Optical Mold Cavity Mirror Finishing & Assembly Alignment

## 14.1 Mirror Milling & Surface Roughness Specifications
For precision mold cavities (utilizing premium steels such as **ASSAB S136 / BÖHLER STAVAX ESR**):

* **Optical Surface Finish**: Mirror milling and ultra-precision EDM achieve surface roughness down to **Ra < 0.08 µm** ($Sa < 18\text{nm}$).
* **Manual Polishing Elimination**: High-speed mirror milling directly generates optical-grade cavity surfaces, reducing or completely eliminating manual hand-polishing error and preserving GD&T edge acuity.

## 14.2 "Ready-to-Assemble" Mold Assembly Tolerances
To guarantee seamless mold interchangeability and zero-flash liquid silicone rubber (LSR) / micro-molding performance:

* **Core & Cavity Alignment Tolerance**: **±0.003mm to ±0.005mm** positional concentricity.
* **In-House Tool Assembly Protocol**: Core-to-cavity alignment, guide pin pre-loading, and parting line shut-off checks are performed inside a climate-controlled assembly cell using CMM live alignment.
