# Industrial Specification: Robotic Coating Spray Arm

## 1. Technical Definition
Robotic arm component designed for precise application of coating materials onto mold surfaces

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-2.5 m/s nozzle velocity, 0.3-1.2 MPa fluid pressure, ±0.05 mm positional accuracy**. Failure boundary: **Fluid pressure exceeding 1.5 MPa causes hose rupture, nozzle velocity below 0.5 m/s creates uneven coating, positional deviation beyond ±0.15 mm causes pattern distortion**, Mechanism: **Hose rupture occurs due to hoop stress exceeding 25 MPa yield strength of polyurethane material. Uneven coating results from Reynolds number dropping below 2000 (laminar flow regime). Pattern distortion happens when servo motor torque exceeds 12 Nm at maximum extension, causing gear slippage.**.

### 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.
