# Industrial Specification: Coordinate Measuring Machine (CMM)

## 1. Technical Definition
A precision measurement device used to inspect the dimensional accuracy of manufactured parts.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-40 μm measurement uncertainty, 0.1-2.5 m/s probe speed, 15-25°C temperature range**. Failure boundary: **Measurement uncertainty exceeds 40 μm, probe collision force exceeds 0.5 N, thermal expansion compensation fails at ΔT &gt; 0.5°C/min**, Mechanism: **Thermal expansion mismatch between granite base (α=8×10⁻⁶/°C) and steel scales (α=12×10⁻⁶/°C) causing dimensional drift; Hertzian contact stress exceeding 1.2 GPa at ruby probe tip (E=400 GPa) inducing permanent deformation**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$  
> **Engineering Impact**: Defines the precision confidence interval for inspection.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in CMM construction and why?
**A**: CMMs use granite for the base/table for stability and thermal resistance, aluminum or steel alloy for the bridge/gantry for strength-to-weight ratio, ceramic for guideways for wear resistance and smooth movement, and stainless steel for probe components for durability and corrosion resistance.

### Q: How does a CMM ensure measurement accuracy in manufacturing?
**A**: CMMs ensure accuracy through rigid granite bases that minimize vibration, precision ceramic guideways that reduce friction, high-resolution probes, and sophisticated controller systems that compensate for environmental factors like temperature variations.

### Q: What are the key components of a Coordinate Measuring Machine?
**A**: Key components include: the machine structure (bridge/gantry for movement), probe head (holds measurement probes), measurement probe/stylus (contacts parts), granite table/base (stable measurement platform), and controller/drive system (controls movement and processes data).
