Short-Term Certificate (2-3 semesters)

At a Glance

Our program instructs students in the process of manufacturing metal parts. This is accomplished by using machine tools to remove excess material like a woodworker cuts away excess wood to produce his work. In addition to metal, the parts may be made of many other kinds of materials. The goal of these cutting operations is to produce a part that conforms to a set of specifications usually in the form of engineering drawings commonly known as blueprints.

Program Description

This program offers an Associate in Applied Science (AAS), Certificate, and Short-Term Certificates. The machining/computer numerical control program prepares students to enter the skilled manufacturing workforce as highly trained employees. The tool and die students learn to shape, form or cut metal work pieces into blueprint specific tools for industry using high-tech machines and modern software. 

Program Expectations

Students will learn the skills needed to carry through to completion the construction and repair of machine parts using machinist’s hand tools, machine tools, and precision measuring instruments. Students will then learn to read blueprints and to set up and operate machinery such as engine lathes, milling machines, cylindrical grinders, surface grinders, and drill presses. Students will also be trained in the programming and operation of highly technical computer-controlled lathes, milling machines and wire electrical discharge machines.

Career Path

Careers as machinists, CNC operators and programmers, tool and die makers, tool machinery and sales, and quality control inspectors are just a few that will be available to graduates of this program. 

Excellent job opportunities are expected. Employers in certain parts of the country report difficulty attracting qualified applicants. The median annual wage for machinists was $50,840 in May 2023. The lowest 10 percent earned less than $36,690, and the highest 10 percent earned more than $75,820. Computer Numerically Controlled Tool Programmers average earnings in May 2023 was $30.50 per hour or $63,440. Experienced machinists may be promoted to supervisory or administrative positions in their firms, increasing their earning power. (Source: U.S. Department of Labor Bureau of Labor Statistics)
