My CNC Mill is finally completed after about 9 months of obsessive effort. I have already milled a few parts for a second CNC machine, a plastic doggy bone and a few PCBs have been drilled and routed. The plastic doggy bone was only 1 x 1/3 inches but the detail was fantastic!
The accuracy exceeds the measurability of my digital caliper (1/2mil resolution) so I am quite impressed with the results! So far, I am limiting my materials to plastic, machinable wax and Butterboard(tm) but will cut some aluminum shortly.
I have included some details on the construction with a few pictures.
An Introduction by Ed Nisley
Watch an informative introduction to CNC design by Ed Nisley. If you are new to CNC, watch it! One thing it illustrates is a CNC machine is not like your printer! In other words, creating cnc parts is not a draw your workpiece and hit print process. There are a few important steps in between.
