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 … See more The process starts by printing the shape of the part onto optically clear and dimensionally stable photographic film. The "phototool" consists of two sheets of this film showing negative images of the parts (meaning that … See more Thin gauge (under 0.050 in (1.3 mm)) parts in a broad range of alloys are candidates for photo etching. Industrial applications include fine screens and meshes, apertures and masks, battery grids, fuel cell components, sensors, springs, pressure membranes, See more Phototooling is quick and inexpensive to produce. Most phototools costs less than $350 and can be produced in two days or less. Unlike "hard" … See more WebAbout the Photo Chemical Machining Institute The PCMI was founded in 1967.
