# Industrial Specification: Cutter Head

## 1. Technical Definition
The rotating cutting assembly at the front of a foundation drilling machine that excavates soil and rock.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 MPa hydraulic pressure, 5-25 RPM rotational speed, 50-150 kN axial thrust**. Failure boundary: **Hydraulic pressure exceeding 40 MPa causes seal extrusion, rotational speed exceeding 30 RPM induces centrifugal force &gt; 2.5g leading to bearing race spalling, axial thrust exceeding 180 kN initiates Hertzian contact stress &gt; 1.2 GPa at bearing interfaces**, Mechanism: **Hydraulic seal failure occurs via extrusion when pressure differential exceeds seal material yield strength (EPDM rubber: 15 MPa). Bearing fatigue initiates when alternating shear stress amplitude exceeds 0.55 times material endurance limit (SAE 52100 steel: 550 MPa). Tooth fracture occurs when bending stress exceeds 0.8 times ultimate tensile strength (AISI 4340 steel: 745 MPa) under impact loading.**.

### 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.
