New technologies displaced manual punchcutting from the mid-nineteenth century. Electrotyping from the 1840s is a technology used to form matrices of copper by electrodeposition around engravings of a letterform. This letterform could be in any metal, so engraving increasingly began to be done by cutting a letterform in soft typemetal.
Other terms often used for printed engravings are copper engraving, copper-plate engraving or line engraving. Steel engraving is the same technique, on steel or steel-faced plates, and was mostly used for banknotes, illustrations for books, magazines and reproductive prints, letterheads and similar uses from about 1790 to the early 20th century, when the technique became less popular, except ...
Engraving/milling; Laser marking; LaserShot peening; Liquid metal jet; Stencil (mechanical cut, photo process, laser cut) Other methods like manual metal stamp, vibro-etch and embossing were not suitable to successfully apply micro size (1/32- to 15/64-inch square), high density machine-readable symbols.

The ruling machine created parallel straight or wavy lines very close together, usually for use with etching. [6] Another of these tools is the geometric lathe. The lathe is used to engrave images on plates, which are in turn engraved on rolls for such uses as printing banknotes. Another of these tools is the engraving machine.
Sheet metal embossing is a metalworking process for producing raised or sunken designs or relief in sheet metal. In contrast to coining (which uses unmatched dies), embossing uses matched male and female dies [ 1 ] to achieve the pattern, either by stamping , or by passing a sheet or strip of metal between patterned rollers .

Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. This type of machining was originally performed mechanically on large complex machines.
