This, therefore, is mathematics: she gives life to her own discoveries; she awakens the mind and purifies the intellect; she brings light to our intrinsic ideas; she abolishes the oblivion and ignorance which are ours by birth.

These are the drawings for the IE paperweight that my group (me, Jessica Fulton, and Paxton Smith) designed for our “Manufacturing Engineering II” class during the Spring of 2002. Paxton did most of the drawing (though I did some as well), but the three of us were involved in the design and the machining.
From the syllabus:
One laboratory project with two separate phases: phase I Design and Process Planning and phase II CNC will be assigned in this course.
From our report:
The part we have designed is intended for desktop use. The part is decorative: one side features Texas Tech’s famous “Double T” logo while the other side reads “IE.” The part can also serve a purpose as a paperweight and/or a penholder. It comes equipped with four pen-sized holes (two on either side), making it a practical and stylish addition to any desktop (particularly any desktop that belongs to a Texas Tech Industrial Engineer).
The design was machined from a 2in X 4in X 6in block of aluminum. Aluminum was chosen because of its lightweight, easy-to-machine nature. It was also our only option. A brief description of the part’s features follows. Detailed design drawings of the part are included in Appendix A.
The completed part is 6in in length, 1.75in wide, and 4in in height. A 1in X 3in rectangle was cut from either side of the part. The “Double T” logo is on the front of the part, raised 0.13in from its surroundings. The curved portion of the front of the part, also raised 0.13in, reads “Texas Tech University” (this is not reflected on the drawings in Appendix A, due to the fact that these drawings were created with Autodesk Inventor and the text was added with Surfcam The “IE” on the back of the part is also raised 0.13in from the rest of that side. In the space below the raised “IE”, the names of the group members have been carved (these names, like “Texas Tech University” on the part’s front are not shown in Appendix A).
On either side of the large central portion of the part are two steps. In each step, 0.5in deep holes with diameter of 0.37in have been drilled. These will serve as the penholders and increase the part’s practicality.

The machine used in the machining of the IE Paperweight is a HAAS VF Series Vertical Machining Center. It is a computer numerical controlled (CNC) machine. Thus, drawings made using computer-aided design (CAD) software were translated into G code, which formed the program for the machining of the part.
