This thesis is a study of the ability of a CNC milling machine to create parts for itself, and an evaluation of whether or not the machine is able to improve itself by creating new machine parts. This will be explored by using off-the-shelf parts to build an initial machine, using 3D printing/rapid prototyping to create any special parts needed for the initial build. After an initial working machine is completed, the design of the machine parts will be adjusted so that the machine can start producing its own machine parts, replacing the 3D printed parts. It is desirable for the finished machine to have as many self-created parts as possible. As a physical machine will be built, the steps needed to create the machine will be detailed, so that the machine can be replicated if desired. The finished machine will not be autonomous, but will rely on a human operator to design the parts and operate the machine.
