2. Photochemical machining - Wikipedia

   en.wikipedia.org/wiki/Photochemical_machining

   Photochemical machining (PCM), also known as photochemical milling or photo etching, is a chemical milling process used to fabricate sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960s as an offshoot of the printed circuit board industry.
