How Do CNC Machines Work?
CNC machines operate through the use of:
Computer Software (CAD/CAM):
CAD (Computer-Aided Design) is used to design parts, while CAM (Computer-Aided Manufacturing) converts those designs into instructions (G-code).
G-Code Programming:
This code tells the machine how to move — including direction, speed, feed rate, and tool path.
Controllers and Motors:
CNC controllers interpret the code and command the motors to move the cutting tools accordingly.
Tooling:
Depending on the machine type, tools like drills, end mills, cutters, or laser heads are used to shape the material.
