# Industrial Specification: Workpiece Clamping System

## 1. Technical Definition
A mechanical system within the Edge Preparation Unit that securely holds and positions workpieces during edge preparation operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 MPa clamping pressure, 0.01-0.05 mm positional tolerance, -20°C to 80°C operating temperature**. Failure boundary: **Clamping pressure below 0.3 MPa causes workpiece slippage exceeding 0.1 mm; pressure above 3.5 MPa induces permanent deformation in aluminum workpieces; temperature beyond 100°C degrades polymer seals**, Mechanism: **Clamping force below 0.3 MPa yields insufficient static friction (μs=0.15 for steel-aluminum interface) to overcome cutting forces; pressure above 3.5 MPa exceeds aluminum yield strength (σy=280 MPa) at contact points; thermal expansion coefficient mismatch (αsteel=12×10⁻⁶/°C, αaluminum=23×10⁻⁶/°C) causes binding at 100°C**.
