# Industrial Specification: Positioning Stage

## 1. Technical Definition
A precision mechanical component that provides controlled linear or rotational movement for accurate positioning within the Precision Stacking Head assembly.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 μm positioning accuracy, 0-100 mm/s velocity, 0-50 N load capacity**. Failure boundary: **Positioning error exceeds 0.5 μm RMS, backlash exceeds 0.2 μm, repeatability exceeds 0.1 μm**, Mechanism: **Ball screw wear (Archard's wear equation: K=2.5×10⁻⁷), linear guideway deformation (Young's modulus E=200 GPa), thermal expansion (α=11.7×10⁻⁶/°C for steel)**.

### 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.
