# Industrial Specification: Rotating Worktable

## 1. Technical Definition
A precision rotating platform that holds and positions workpieces during machining operations on a CNC vertical lathe.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-3000 rpm with ±0.001° angular positioning accuracy**. Failure boundary: **Exceeding 3500 rpm causes bearing raceway spalling due to centrifugal forces exceeding 1.5 GPa yield strength of AISI 52100 steel**, Mechanism: **Hertzian contact stress exceeding material fatigue limit at 1.2 GPa, leading to subsurface crack initiation and propagation through rolling contact fatigue mechanism**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
