The purpose of this lab was to gain an understanding of a few general machining processes through hands on operation while manufacturing a bolt. For this lab we were introduced to two machines available in the machine shop. The first piece of equipment we used was the lathe. A lathe is a machine which turns a piece of material to be modified. This material is usually a piece of bar stock or another form of round material. The three main machining processes we discussed in lab were turning, boring, and facing. Turning is using a tool to cut into the outside of the spinning material in order to reduce its diameter. Boring is removing material from the inside of the piece, starting at the center and working your way out until the required inner diameter is reached. The last procedure, facing, is using a tool to cut material off of the end of your piece to produce a flat end. The second piece of equipment we used was the Bridgeport manual mill. A manual milling machine is used for shaping various materials but most commonly metal. The mill is based around a rotating cutter called an end mill which rotates around the spindle axis. The second most important part of the mill is the table. The table is the area to which the work material is attached, usually through a vise or clamps. The table can be moved in the X, Y, and Z directions in order to generate the desired tool path. The movement in these directions is controlled by the handles on the sides of the table and on the knee of the machine and is very precise. The machine itself also has different gears that allow the user to change the spindle speed in order to compensate for the material being cut. During this lab we made a ½-UNF20 x 3⅝ bolt.
