# Industrial Specification: Fastener Feeder

## 1. Technical Definition
A component that automatically supplies fasteners to the fastening tool in an automated assembly system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar supply pressure, 0.1-2.0 mm fastener diameter tolerance, 15-60 fasteners/minute feed rate**. Failure boundary: **Supply pressure below 0.3 bar causes jamming; vibration amplitude exceeding 0.5 mm RMS disrupts orientation; fastener diameter variation beyond ±0.05 mm from nominal causes misfeeds**, Mechanism: **Stiction-induced jamming at low pressure due to Coulomb friction exceeding pneumatic force; resonant vibration at 25-40 Hz natural frequency causing misalignment; geometric interference from dimensional tolerance stack-up**.

### 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 |

| \omega | Angular Frequency | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contaminant ingress (ISO 4406 Class 18/16/13 exceeded) in pneumatic supply | 8 | Spool valve seizure due to particulate accumulation in 0.8 mm orifice | Install 5 μm absolute filter with differential pressure sensor (0.2 bar threshold alarm) |
| Electromagnetic interference from adjacent 400 Hz VFD drives exceeding 10 V/m field strength | 8 | Solenoid driver IC latch-up causing continuous actuator energization | Shielded enclosure (30 dB attenuation at 400 Hz) with ferrite chokes on control cables |
