# Industrial Specification: Lance Gripper / Clamp

## 1. Technical Definition
A mechanical clamping device designed to securely hold and position the lance within a manipulator system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kN clamping force, 0.01-0.1 mm positional accuracy, -20°C to 80°C ambient temperature**. Failure boundary: **Clamping force drops below 0.3 kN, positional deviation exceeds 0.15 mm, temperature exceeds 100°C**, Mechanism: **Yield strength exceedance of AISI 4140 steel (415 MPa) causing permanent deformation, thermal expansion coefficient mismatch (11.7 μm/m·K for steel vs 23.1 μm/m·K for aluminum) inducing binding, Hertzian contact stress exceeding 1.5 GPa causing surface pitting**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
