# Industrial Specification: Probe Head

## 1. Technical Definition
The component of a Coordinate Measuring Machine (CMM) that houses the probe and enables its precise positioning and orientation during measurement operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-50 N contact force, 0.5-1000 mm/s positioning speed, ±0.5 μm positioning accuracy**. Failure boundary: **Contact force exceeding 50 N causes permanent probe stylus deflection &gt;2 μm, positioning speed &gt;1000 mm/s induces vibration amplitude &gt;0.1 μm RMS**, Mechanism: **Yield strength of tungsten carbide stylus (6000 MPa) exceeded at 50 N contact force, critical damping ratio of 0.7 violated at 1000 mm/s causing resonant vibration**.

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