# Industrial Specification: Linear Positioning Stage

## 1. Technical Definition
A precision mechanical component that provides controlled linear motion along a single axis.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1000 mm travel, 0.1-500 mm/s velocity, 0.1-10 m/s² acceleration**. Failure boundary: **Ball screw pitch error exceeds 5 μm/300 mm, linear guideway preload drops below 0.02C dynamic load rating, positioning repeatability exceeds ±0.5 μm**, Mechanism: **Hertzian contact stress exceeding 4200 MPa causes ball bearing raceway spalling, thermal expansion mismatch (Δα=11.5×10⁻⁶ K⁻¹) between aluminum carriage and steel rails induces binding at ΔT&gt;50°C, lubricant starvation leads to boundary lubrication regime with friction coefficient μ&gt;0.15**.

### 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.
