# Industrial Specification: Cam Mechanism

## 1. Technical Definition
A mechanical component that converts rotational motion into linear motion or vice versa within a locking system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 N·m torque input, 0.01-50 mm linear displacement output, 0-120° cam angle rotation**. Failure boundary: **Hertzian contact stress exceeding 1.5 GPa at cam-follower interface, surface roughness Ra &gt; 0.8 μm at sliding surfaces, cam shaft deflection &gt; 0.05 mm per 100 mm length**, Mechanism: **Surface fatigue failure due to cyclic Hertzian contact stress exceeding material endurance limit (typically 0.4-0.5 of ultimate tensile strength for steel), adhesive wear from boundary lubrication breakdown when Stribeck parameter &lt; 0.001**.

### 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.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient lubrication film thickness (λ &lt; 1) at cam-follower interface | 8 | Accelerated adhesive wear leading to surface scoring and increased friction coefficient from 0.1 to &gt;0.3 | Implement forced lubrication system with minimum 0.02 mm oil film thickness, specify surface hardness &gt; 58 HRC with DLC coating (coefficient of friction 0.05-0.1) |
| Cyclic bending stress exceeding material fatigue limit at cam shaft fillet radius | 8 | Fatigue crack initiation and propagation at stress concentration points (Kt &gt; 2.5), leading to shaft fracture | Design fillet radius ≥ 3 mm with shot peening to induce 400-600 MPa compressive residual stress, use vacuum-melted steel with inclusion rating ≤ 1.5 per ASTM E45 |
