John Wood Community College professor instructs student on using manufacturing computer equipment

Precision Machining (CNC) Machinist

Building on the certified production technician certificate, the six classes for the precision machining certificate focus on computer numeric controlled (CNC) automated machinery used to produce parts from metal, plastic, or other materials. CNC machinists make adjustments to control capacity, perform periodic checks, and review the finished product to ensure readiness for the next step in production.
