What a machinist does
Machinists set up and operate lathes, mills, grinders and CNC machining centers to cut metal parts to tolerances measured in ten-thousandths of an inch. You'll read engineering drawings and GD&T, write and prove out CNC programs, select tooling and speeds, and inspect your own work with precision instruments. It's the thinking person's trade – math, materials and machines, all day.
Every manufactured thing in America passes through a machinist's hands somewhere: jet engines, submarine components, medical implants, tooling and dies. The defense industrial base build-out and the reshoring of manufacturing have made experienced machinists chronically scarce – about 34,200 openings are projected every year through 2034, driven by a wave of retirements that new CNC technology can't fill on its own.
Apprenticeships and NIMS-credentialed programs pay you while you learn, and skills compound fast: CNC programmers, tool and die makers and shop leads command premium pay. If you like solving puzzles in metal, this trade rewards precision for an entire career.
