The metalworking industry needs more CNC operators. This rewarding career appeals to people who have a broad skill set: a good eye for detail, math, mechanical design, and the ability to read technical drawings. CNC operators use a combination of brains and hands-on work to properly transform a metal casting into a valuable working machined part.
The goal of modern CNC milling is to transform materials such as metal castings into finished, usable parts. That goal is only achievable by using incredibly precise CNC milling machines.
Computer software is the brains of a CNC (Computer Numerical Control) milling machine, controlling the machine and automating production to increase throughput with consistent quality. It’s this repeatability that makes CNC machining so efficient and so valuable to both customers and the machinists themselves (see “The Machinist’s Perspective” throughout this article.)
