# Industrial Specification: Positioning Actuator

## 1. Technical Definition
A mechanical or electromechanical device that precisely controls the position of coating heads or nozzles within a precision coating applicator system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 μm positioning accuracy, 0-500 mm/s velocity, 0-100 N force**. Failure boundary: **Positioning error exceeds ±0.5 μm from commanded position, backlash exceeds 0.2 μm, repeatability error &gt;0.1 μm**, Mechanism: **Ball screw thermal expansion (coefficient 11.7×10⁻⁶/°C for steel), bearing preload loss due to Hertzian contact stress exceeding 1.5 GPa, encoder interpolation error at &gt;16-bit resolution**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Lubricant degradation at 80°C operating temperature | 8 | Ball screw stick-slip friction coefficient increases from 0.002 to 0.008 | Integrated Peltier cooling maintains 40±2°C, ceramic-coated balls (Al₂O₃) reduce adhesion |
| Encoder signal interference from 400 Hz VFD harmonics | 8 | Position feedback phase error &gt;0.5° causes 2 μm positional oscillation | Differential line drivers with 100 dB CMRR, shielded twisted-pair cables with 360° termination |
