# Industrial Specification: Mechanical Positioning System

## 1. Technical Definition
A precision mechanical system that accurately positions components or sensors within an Automated Optical Inspection Unit for defect detection and measurement.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 μm positioning accuracy, 0-50 N axial load capacity, -10°C to 60°C operating temperature**. Failure boundary: **Positioning error exceeds 0.5 μm RMS, backlash exceeds 0.2 μm, linear bearing wear exceeds 10 μm clearance**, Mechanism: **Ball screw thermal expansion (α=11.5×10⁻⁶/°C for steel) causing positioning drift, Hertzian contact stress exceeding 1.5 GPa in linear bearings leading to Brinell deformation**.

### 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.
