If you've ever taken shop class in high-school or watched an episode of how it's made, you have probably have some idea how lathes and other metalworking machines function. As technology and computers have improved over the years, a new high-precision computer controlled manufacturing technique called CNC machining has spawned.
CNC machines, or computer numerically controlled machines, are electro-mechanical devices that can manipulate tools around a varying number of axis, usually 3 or 5, with high-precision per instruction from a computer program. CNC machining is one of two ways that engineers, machinists, or makers can generate a physical part from a computer design file, with the other being 3D printing, known as additive manufacturing.

CNC. The only job you'll love to hate. Been doing this for almost 10 years now. The good out weighs the bad, but when the bad hits it sucks.

[@ISILENTNINJAI]

Getting a 1st time run is always fun. Gotta be on you're toes. Like they say A great engineer/programmer can make your job manageable as a machinist. And a bad one will help you learn through experience fixing their screw ups.

[@JustAGuyWithALongScreenName]

I work as a cnc machinist for over 9 years now, planing to open my own shop now, have the ability to buy and programm turning and milling machnes also good at programming robot hands, also have experience in 5 axis programming, but mostly we run same parts so not so much programming there, programm in Siemens NX. Love my job, where i work is very clean, fun people, always something new to learn. Its a job where you always learn something new, it has no boundries what makes it fun for me. Love it! but its not for everyone.

@@ckompadavid138 the only thing I can recommend is that you pay very close attention to a very good CNC machinist. It's a lot to take in the beginning, but given time you'll be fine. One very important thing. Before you run a program on the CNC run it through a blank cycle. The reason I say that is because sometimes the programmer sometimes places decimals in the wrong spot. Just take your time and read every line in the program.
