# Industrial Specification: Feeding Arm

## 1. Technical Definition
A mechanical arm component within a bolt feeder mechanism responsible for transferring bolts from storage to the feeding position.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 NÂ·m torque, 0.1-0.5 m/s linear velocity, 0.05-0.15 mm positioning accuracy**. Failure boundary: **3.0 NÂ·m torque exceeds gear train yield strength, 0.6 m/s velocity exceeds servo motor thermal limit, 0.2 mm positioning error exceeds bolt clearance tolerance**, Mechanism: **Gear tooth pitting fatigue at 10^7 cycles under 2.8 NÂ·m load, servo motor winding insulation breakdown at 85Â°C ambient temperature, linear bearing seizure at 0.01 mm particulate contamination**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
