# Industrial Specification: Vial Positioning Nest

## 1. Technical Definition
A precision fixture component within a stoppering station that securely holds and positions vials during the sealing process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 N clamping force, 0.01-0.05 mm positional tolerance, 15-35°C operating temperature**. Failure boundary: **Clamping force exceeds 8.0 N causing vial deformation, positional error exceeds 0.1 mm causing misalignment, temperature exceeds 50°C causing thermal expansion beyond 0.02 mm**, Mechanism: **Excessive clamping force induces plastic deformation via von Mises yield criterion (σ_vm &gt; 250 MPa for 316L stainless steel), thermal expansion mismatch (α_vial=8.5×10^-6 K^-1 vs α_nest=17.3×10^-6 K^-1) creates interfacial stresses exceeding 150 MPa**.

### 2.1 Analytical Physics Model
Governed by the **Rayleigh Resolution Criterion**:

> **Primary Equation**: $d = \frac{0.61 \lambda}{NA}$  
> **Engineering Impact**: Defines the theoretical limit of machine vision systems.
