Synonyms
CHM, generic term for the entire family of chemical machining processes including chemical milling of pockets or cavities (Bellows 1977); PCM, photochemical machining, also commonly known as photoetching, photomilling, photochemical milling, photofabrication, and chemical blanking (Allen 1986, 2016)
Definition
In terms of a production engineering process (Allen 2004), etching is better defined as a material removal process by accelerated, controlled corrosion, comprising a heterogeneous chemical reaction in which a liquid (or, more rarely, a gas) reacts with a solid material and oxidizes it to produce a soluble (or volatile gaseous) reaction product.
Theory and Application
Etching as a Process Employed in Manufacturing and Production Technology
The “art” of etching (Chamberlain 1972) was developed into a production process for the graphic arts, printing, and die-making industries, utilizing chemical etching and photoresist imaging to produce printing plates and dies by...
