Choosing the Right Path

So, how do you decide? Ask yourself these questions:

Am I brand new to CNC machining? → Community college or apprenticeship might be best.
Do I want a career in a specific company or industry? → OEM or employer-sponsored certifications win.
Am I already experienced but need formal proof? → NIMS or online certifications can validate your skills.

Funny Fact 🤔

Did you know some CNC operators jokingly say their first “certification” came from not crashing a spindle for six months? While true experience matters, official certifications look a lot better on a résumé.

Lesser-Known Fact 💡
