As part of the first ENGD class, students machine a top out of brass. This gives students who may not have machined in the past a chance to use a mill and a lathe. We are given a diagram and are taught how to use the machines to get the top to match the diagram. We also have to get the top within certain tolerances in order for it to work properly. We use the lathe to get the top part of the top to be a set size and length, then we cut off excess material and use the lathe to get a 20 degree angle. After that we use the mill to put four holes in the top and to take off a little bit of material from the sides.
