# Industrial Specification: Fastener Installation Module

## 1. Technical Definition
Automated module for installing fasteners in computer chassis assembly

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-2.5 NÂ·m torque, 4-6 mm fastener travel, 0.1-0.3 mm positional accuracy**. Failure boundary: **Torque exceeding 3.2 NÂ·m causes gearbox shear failure at 450 MPa yield strength, positional error &gt;0.5 mm causes cross-threading**, Mechanism: **Fatigue failure in planetary gear teeth due to Hertzian contact stress exceeding 1.2 GPa at 10^7 cycles, thermal expansion mismatch between steel drive shaft (Î±=11Ã—10^-6/Â°C) and aluminum housing (Î±=23Ã—10^-6/Â°C) causing binding at Î”T&gt;40Â°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Servo motor encoder contamination by metallic dust particles &gt;5 Î¼m | 8 | Positional feedback loss causing 0.8 mm overshoot in fastener placement | IP67-rated encoder housing with positive-pressure nitrogen purge at 1.2 bar |
| Lubricant degradation in harmonic drive at 80Â°C operating temperature | 8 | Torque transmission loss of 35% resulting in 1.8 NÂ·m actual vs 2.5 NÂ·m target | Synthetic perfluoropolyether lubricant with 200Â°C thermal stability and automatic replenishment at 1000-cycle intervals |
