514: Safe CNC

This project improves the safety of a computer numerical control (CNC) milling machine used by students and staff in the FAMU-FSU College of Engineering’s senior design lab. The CNC milling machine helps cut metal and plastic but poses safety risks including moving parts, flying debris, sharp edges and airborne dust, which can cause injuries or breathing problems. The goal is to create a safer workspace for students by protecting them from these risks.

To manage these risks, we designed an enclosure with four key features. First, we built a physical barrier that prevents contact with moving parts and contains debris and dust. Second, we installed an automatic shutoff system that stops the machine if doors open during operation. Third, we added a manual emergency stop button outside the enclosure for quick shutdown during emergencies. Finally, we integrated a vacuum system that removes fine dust to keep air clean, improve visibility and prevent dust buildup.

By adding these safety features, our project created a safer and cleaner CNC milling environment. These improvements protect users while maintaining machine reliability. The simple design allows for future modifications and additional safety features as needed, ensuring long-term safety and functionality.
