Machine Tool Technology (MACH), AAS
At Dunwoody College of Technology, the Machine Tool Technology program provides students with entry-level skills and theoretical knowledge to program and operate all of the latest machine tools utilized in modern manufacturing facilities.
Graduates from this program are prepared to enter the industry as machine operators, production machinists, CAD/CAM technicians, CNC programmers, and tool designers.
The course of study includes: manual milling and turning; measurement and materials; job planning and layout; CAD/CAM software; CNC milling and turning; mold and die making; and EDM technology.
The program's curriculum is closely aligned with standards set forth by the National Institute of Metalworking Skills (NIMS). Due to high demand, most machine tool students can find full-time employment in the field long before graduation, and many will be working in a shop within the first year of the program.
Arts & Sciences curriculum supports the technical coursework by enhancing the students' communication, mathematics, and critical thinking skills.
