Machining Technology
Course Description:
Machinists are highly skilled men and women. They use drawings and
blueprints, hand tools, precision measuring tools, drilling machines,
band saws, surface grinders, lathes, milling machines, and other
specialized machine tools to shape and finish metal and nonmetal
parts. Machinists must have a solid understanding of basic and advanced
machining techniques, which includes:
- Proficiency in safely operating machine tools of various
types (manual, automatic, and computer numeric controlled).
- Knowledge of the working properties of metals and nonmetals.
- The academic skill (math, science, English, print reading,
metallurgy, etc.) needed to make precision layouts and machine
set-ups.
Machine Tool Technology provides and introduction to this important
area of Manufacturing Technology. The course explains the “how,
why, and when” of numerous machining operations, set-ups, and
procedures. Through it, students will learn how machine tools operate
and when to use one particular machine instead of another. The advantages
and disadvantages of various machining techniques are discussed,
along with their suitability for particular applications. The students
will demonstrate their skill and understanding through manufacturing
several hands-on projects.
