2004· Photochemical Machining: from ‘manufacturing’s best kept secret’ to a $6 billion per annum the basic operations are similar.Photochemical machining is one of the non-conventional machining processes that can produce complex shapes[1]. PCM is also known as photochemical milling or photo etching. It is chemical milling process used to fabricate sheet metal components using photoresist and etchant to removePhotochemical machining (PCM) is one of the least well-known non-conventional machining processes. It employs chemical etching through a photoresist stencil as the method of material removal over selected areas. The technique is relatively modern and became established as a manufacturing process about fifty years ago. The processing technology has been kept a closely-guarded secret within a ...milling of pockets
