Not exactly, "machining" but metal work all the same. I just finished a pair of necklaces for my sister. They are enamel on copper. I figured some folks would be interested.
The first shot shows the domed copper disk that will be the base of everything. Next to that is the rectangular silver wire that will form the boundaries between colors.
Next shot shows the copper disk with a base coat of glass (enamel) fused on, and the wires glued in place.
Then we see the compartments packed with powdered enable, ready to be fused in the kiln.
A shot of the second necklace just before firing the background color.
Both necklaces finished. The surface has been ground down with an aluminum oxide stone under water so that everything is flush.
