# Industrial Specification: Tool Gripper / Arm

## 1. Technical Definition
Mechanical component of an Automatic Tool Changer that physically grasps, holds, and manipulates tools during the exchange process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Gripping force: 150-1200 N, Jaw travel: 0-25 mm, Positioning accuracy: ±0.02 mm, Maximum tool weight: 15 kg**. Failure boundary: **Gripping force below 100 N causes tool slippage, jaw misalignment exceeding 0.05 mm prevents proper tool seating, actuator pressure below 6 MPa results in insufficient clamping force**, Mechanism: **Mechanical wear at jaw contact surfaces reduces friction coefficient below μ=0.15, thermal expansion of aluminum actuator housing creates 0.03 mm clearance at 80°C, hydraulic fluid viscosity drop below 32 cSt at 60°C reduces pressure transmission efficiency**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Pneumatic cylinder seal degradation from 100 ppm oil contamination in compressed air | 8 | Actuator pressure loss from 0.7 MPa to 0.3 MPa within 50 cycles | Install coalescing filter with 0.01 μm rating and desiccant dryer maintaining -40°C dew point |
| Servo motor encoder misalignment of 0.5° due to mounting bolt torque variation exceeding ±15% | 8 | Position feedback error accumulation of 1.2 mm after 100 positioning cycles | Implement laser alignment procedure with 0.01° tolerance and digital torque wrench with 2% accuracy |
