# Industrial Specification: Automated Fastening System

## 1. Technical Definition
A robotic system that automatically installs fasteners (bolts, screws, rivets) during automotive chassis assembly.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 NÂ·m torque range with Â±0.05 NÂ·m accuracy, 4-6 bar pneumatic pressure, 0.5-2.0 m/s linear speed**. Failure boundary: **Torque exceeding 1.5 NÂ·m causes fastener stripping; pressure below 3.5 bar results in incomplete fastener seating; misalignment &gt;0.2 mm causes cross-threading**, Mechanism: **Yield strength of M6 steel fasteners (640 MPa) exceeded at 1.5 NÂ·m; Bernoulli's principle explains pressure drop effects; Hertzian contact stress causes misalignment failures**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

| Symbol | Variable Definition | Localized Reference |

| m | Eccentric Mass | Engineering Constant |
| r | Radius | Engineering Constant |
| \omega | Angular Frequency | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Pneumatic supply contamination with 15 Î¼m particles | 8 | Valve stiction causing 300 ms actuation delay | Install 10 Î¼m absolute filters with differential pressure monitoring |
| Servo motor encoder resolution degradation to 12-bit from 16-bit | 8 | Positional accuracy loss exceeding Â±0.1 mm tolerance | Implement dual redundant encoders with majority voting logic |
