# Industrial Specification: Electrode Feeding Mechanism

## 1. Technical Definition
A mechanical system responsible for precisely delivering and positioning electrodes within an industrial system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 mm positioning accuracy, 0.5-10.0 N feed force, 0.01-1.0 m/s feed velocity**. Failure boundary: **Positioning error exceeding ±0.15 mm, feed force dropping below 0.3 N or exceeding 12.0 N, velocity deviation beyond ±0.02 m/s from setpoint**, Mechanism: **Servo motor cogging torque exceeding 0.05 N·m at low speeds (0.01-0.1 m/s) due to magnetic slot harmonics, causing position overshoot beyond PID controller compensation capability of ±0.1 mm**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.

- **Caution**: 

### Q: What materials are used in the electrode feeding mechanism construction?
**A**: Our electrode feeding mechanism is constructed from durable stainless steel, lightweight aluminum alloy, and high-performance engineering plastics for optimal strength and corrosion resistance in industrial metal manufacturing environments.

### Q: How does the tension control system improve electrode feeding precision?
**A**: The integrated tension control system maintains consistent electrode tension throughout the feeding process, preventing slippage or over-tightening that could compromise positioning accuracy in critical metal manufacturing operations.

### Q: What maintenance is required for the feed roller assembly?
**A**: The feed roller assembly requires periodic inspection for wear and cleaning to remove metal particulates. Stainless steel construction minimizes corrosion, while sealed bearings extend service intervals in demanding metal manufacturing applications.
