Course Description
Students will learn the proper use of machine tools to manufacture parts from metal alloys, and the importance and proper use of engineering documentation in the development process. Aluminum, primarily due to its ease of machining, will be used to learn basic procedures. Steel will be introduced to illustrate the variation of properties of materials. Students will set up and operate lathes for the first half of the semester and then move on to  milling machines for the second half. They will be required to manufacture, from drawings, parts to tolerances as close as .003  inch. The instructor will ensure the students' safety and ability to accomplish these tasks throughout the course. This course will be invaluable to engineering students, graduate students in all research laboratories, and anyone planning to become involved in a manufacturing environment.

Course Policies
Attendance and timeliness are of utmost importance due to the nature of this class. It is
an ongoing learning process where one operation leads to another so if you miss or come
late often you will fall too far behind to progress. Make-up classes may be possible, depending on instructor's work load.

Safety is a top priority for yourself and those around you. Accidents can happen in a split
second, if you are not alert and concentrating. Most students receive top grades providing they are punctual, try hard, and abide by the rules.

Support Services
The instructor is present all week to answer any questions you may have or any guidance
you may need to excel in this course.
