# Industrial Specification: Cold Milling Machine

## 1. Technical Definition
A heavy-duty construction machine used to remove asphalt and concrete surfaces from roads, bridges, and other paved areas.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-2.5 MPa hydraulic pressure, 15-40 RPM cutter drum speed, 0-300 mm cutting depth**. Failure boundary: **Hydraulic pressure exceeding 3.2 MPa causes seal rupture, cutter drum speed exceeding 45 RPM induces centrifugal failure, cutting depth exceeding 350 mm causes structural deformation**, Mechanism: **Hydraulic system failure due to Pascal's law pressure transmission exceeding material yield strength (σ_y = 250 MPa for SAE 1045 steel), cutter drum failure from centrifugal force (F_c = mω²r) exceeding bearing fatigue limit (L_10 = 10,000 hours at 40 RPM)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| m | Eccentric Mass | Engineering Constant |
| r | Radius | Engineering Constant |
| \omega | Angular Frequency | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level | 8 | Proportional valve spool seizure causing loss of depth control | Install dual-stage filtration with 3 μm absolute rating and real-time particle counting |
| Cutter drum bearing lubrication starvation below 0.1 mm oil film thickness | 8 | Bearing cage fracture leading to drum misalignment and vibration &gt; 7.1 mm/s RMS | Implement forced lubrication system with 0.35 MPa minimum pressure and thermal monitoring |
