# Industrial Specification: Work Fixture / Jig

## 1. Technical Definition
A specialized tool or device used to hold, support, and position workpieces during assembly operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1500 N clamping force, 0.01-0.05 mm positioning tolerance, -20°C to 120°C temperature range**. Failure boundary: **Clamping force exceeds 2000 N causing permanent deformation, positioning error exceeds 0.1 mm causing misalignment, temperature exceeds 150°C causing material degradation**, Mechanism: **Plastic deformation occurs at yield strength of 250 MPa for tool steel, thermal expansion coefficient mismatch (11.7×10⁻⁶/°C for steel vs 23.1×10⁻⁶/°C for aluminum) causes binding, fatigue failure at 10⁶ cycles under 1000 N cyclic loading**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Thermal expansion differential between fixture and workpiece materials | 8 | Workpiece binding during temperature cycling | Implement coefficient of thermal expansion matching materials or thermal compensation mechanisms |
| Clamping force concentration exceeding material yield strength | 8 | Localized plastic deformation at contact points | Distribute clamping force through larger contact areas or compliant interfaces |
