Machine shp majrs will learn f the varius ccupatins in metalwrking and will increase skills in machining prcesses. This is an excellent backgrund curse fr autmtive and drafting majrs. Descriptin This curse directs the student in the use f five basic machine tls: drilling machines, lathe, milling machine, shaper, and precisin grinders. Students will learn t use precisin measuring instruments and layut equipment and t machine prjects t print dimensins.
