# Industrial Specification: Tool Exchange Arm

## 1. Technical Definition
Mechanical arm component of an Automatic Tool Changer (ATC) responsible for physically transferring tools between the machine spindle and tool magazine.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 m/s linear velocity, 0.01-0.05 mm positioning accuracy, 5-25 N·m torque capacity**. Failure boundary: **Exceeding 3.0 m/s velocity causes harmonic resonance, exceeding 0.08 mm positioning error triggers collision detection, exceeding 30 N·m torque causes gear tooth shear at 450 MPa yield strength**, Mechanism: **Resonant frequency mismatch at 15-25 Hz operational range causes structural fatigue, cumulative positioning error from ball screw backlash exceeding 0.005 mm/rev, Hertzian contact stress exceeding 1.5 GPa at bearing interfaces**.

### 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.
