# Industrial Specification: Clamping Arm

## 1. Technical Definition
A mechanical arm component of a positioning fixture that applies controlled clamping force to secure workpieces during manufacturing operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-85 bar hydraulic pressure, 0.5-12.5 kN clamping force, -20°C to 120°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 95 bar causes seal extrusion, clamping force exceeding 15 kN induces permanent plastic deformation in arm structure, temperature exceeding 150°C degrades hydraulic fluid viscosity below 15 cSt**, Mechanism: **Seal failure occurs via extrusion through clearance gaps when pressure differential exceeds 95 bar (Parker Hannifin O-ring design limit). Structural failure follows von Mises yield criterion when equivalent stress exceeds 450 MPa (AISI 4140 steel yield strength). Thermal failure results from Arrhenius equation kinetics where hydraulic fluid oxidation rate increases 10x per 25°C above 120°C**.
