What is CNC machining

Computer Numerical Control machines are automated machines, which are operated by computers executing pre-programmed sequences of controlled commands. CNC machines are essentially the opposite of “old-school” devices that are manually controlled by hand wheels or levers, or mechanically automated by cams alone. Today’s modern CNC machines understand and function using CNC machining language – called G-code – which tells them precise measurements for production, like feed rate, speed, location, and coordination.

Today’s design and mechanical parts for CNC systems are highly automated – unlike the old, dangerous, factory machines you’d think of back in the day. The parts’ mechanical dimensions are defined using computer-aided design (CAD) software, and then translated into manufacturing directives by computer-aided manufacturing (CAM) software. Therefore, it is important to have knowledgeable CNC machinists and programmers in the industry to operate this high-tech machinery.
