# Industrial Specification: Automatic Tool Changer

## 1. Technical Definition
A mechanical device that automatically exchanges tools on a machine tool or robotic system without manual intervention.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m/s linear velocity, 0.1-1.0 MPa hydraulic pressure, -10°C to 60°C ambient temperature**. Failure boundary: **Positional accuracy exceeding ±0.02 mm, hydraulic pressure below 0.08 MPa or above 1.2 MPa, tool holder taper wear exceeding 0.005 mm radial runout**, Mechanism: **Hertzian contact stress exceeding 1.5 GPa at tool holder taper interface causing plastic deformation, hydraulic fluid viscosity dropping below 15 cSt at 40°C leading to seal leakage, cumulative fatigue from &gt;10^6 cyclic loading cycles at stress amplitude &gt;300 MPa**.

### 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.
