2. How the Control System Works: A Step-by-Step Explanation

The control system operates in a closed-loop feedback mechanism, ensuring precision machining:

Programming & Toolpath Generation

Operators input machining parameters (e.g., cutting speed, feed rate) via HMI or CAD/CAM software.
The system generates a toolpath (a series of precise movements) based on the part’s geometry.

Motion Control & Servo Feedback

Servo motors adjust position in real-time using encoders to detect deviations.
If a misalignment occurs, the system corrects instantly via feedback loops.

Force & Thermal Monitoring

Sensors detect cutting forces and temperature fluctuations to prevent tool wear or machine damage.
Advanced systems use AI-driven predictive maintenance to anticipate failures.
