# Industrial Specification: Programmable Clamping Unit

## 1. Technical Definition
A programmable clamping device that provides adjustable holding force and positioning for workpieces in automated fixture systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **5-150 bar hydraulic pressure, 0.1-25 kN clamping force, -10°C to +80°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 180 bar causes seal extrusion, clamping force exceeding 30 kN induces permanent deformation in jaw components, temperature exceeding 100°C degrades hydraulic fluid viscosity below 10 cSt**, Mechanism: **Seal failure occurs via extrusion when pressure differential exceeds seal material's yield strength (EPDM: 15 MPa), structural failure via plastic deformation when stress exceeds jaw material's yield strength (4140 steel: 415 MPa), thermal failure via viscosity breakdown when Arrhenius equation predicts 90% viscosity loss at 100°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level | 8 | Spool valve stiction causing position control error exceeding ±0.05 mm | Install 3 μm absolute filtration with differential pressure monitoring at 0.8 bar threshold |
| PWM frequency mismatch between controller (1 kHz) and servo valve (1.5 kHz natural frequency) | 8 | Resonance-induced pressure oscillation ±12% from setpoint | Implement notch filter at 1.5 kHz with 40 dB attenuation and phase margin &gt;45° |
