# Industrial Specification: Linear Guideway Rail

## 1. Technical Definition
A precision-machined rail that provides a rigid, straight track for linear motion systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150°C temperature, 0-1000 N/mm² compressive stress, 0-5 m/s linear velocity**. Failure boundary: **Surface hardness drops below 58 HRC, surface roughness exceeds Ra 0.2 μm, deflection exceeds 0.01 mm per 100 mm length under 500 N load**, Mechanism: **Surface pitting fatigue due to Hertzian contact stress exceeding material yield strength (typically &gt;1200 MPa for hardened steel), leading to spalling and loss of geometric accuracy**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
