How to Become a CNC Machinist
The education, training, certifications and steps it takes to start working as a CNC machinist, plus how long it takes and where the career can lead.
To become a CNC machinist: (1) build math and blueprint skills, (2) train in machining, (3) start as a CNC operator, (4) move into setup, (5) advance to programming. Most people need about 6–24 months. BLS lists “high school diploma or equivalent” as the typical entry-level education.
5 steps to become a CNC machinist
Build math and blueprint skills
Algebra, geometry and trigonometry are used daily.
Train in machining
Take a technical program or apprenticeship.
Start as a CNC operator
Learn to load parts, measure and adjust offsets.
Move into setup
Learn fixturing, tooling and offsets for new jobs.
Advance to programming
Learn CAM and become a CNC programmer or lead.
