# Industrial Specification: Core Chucking System

## 1. Technical Definition
A mechanical system designed to securely hold and position a core or mandrel during industrial manufacturing processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 kN clamping force, 0.01-0.05 mm concentricity tolerance, 20-80°C operating temperature**. Failure boundary: **Clamping force drops below 0.3 kN, concentricity exceeds 0.1 mm, temperature exceeds 100°C**, Mechanism: **Hysteresis in collet spring steel (Young's modulus 210 GPa) causing permanent deformation, thermal expansion mismatch (α_steel=11×10⁻⁶/°C, α_aluminum=23×10⁻⁶/°C) inducing binding**.

### 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.
