CNC stands for computer numerical control that drives machine tool like engravers or cutting tools to fabricate what you have programmed in your software. It can be compared to a man sculpting an image in a wood but this project can do it for you.
This CNC mill is incredibly cheap because it is made from junks like scrap wood but is without doubt really working well. A Dremel tool is attached at the end of the device and the one that does a lot of work.
Some improvements can be used in this device to make it sturdy so that it can stand the amount of workload needed to create a figure.
