How to Become a CNC Programmer
The education, training, certifications and steps it takes to start working as a CNC programmer, plus how long it takes and where the career can lead.
To become a CNC programmer: (1) learn machining basics, (2) complete a CNC program, (3) work as a CNC machinist, (4) learn CAM software, (5) advance. Most people need about 1–2 years plus shop experience. BLS lists “postsecondary nondegree award” as the typical entry-level education.
5 steps to become a CNC programmer
Learn machining basics
Take shop classes and learn manual and CNC machining.
Complete a CNC program
Study G-code, CAM and setup.
Work as a CNC machinist
Learn tooling, fixturing and real-world problems.
Learn CAM software
Earn software certifications and practice on real parts.
Advance
Move into senior programmer, manufacturing engineer or shop lead roles.
Education and training requirements
Many CNC programmers complete a technical college certificate or associate degree in CNC machining or manufacturing technology. Experience as a machinist is very valuable, and CAM software training is essential.
| Typical entry-level education (BLS) | Postsecondary nondegree award |
|---|---|
