  2. Laser engraving - Wikipedia

    en.wikipedia.org/wiki/Laser_engraving

    The machines for laser engraving and laser marking are the same, so the two terms are sometimes confused by those without relevant expertise. The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser-sensitive polymers and novel metal alloys. [2]

  3. Engraving - Wikipedia

    en.wikipedia.org/wiki/Engraving

    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 ...

    Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- ' all, every ' and γραφ- ' to write ', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...

  5. 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.

    CNC Wire-cut EDM machine 1 Wire. 2 Electrical discharge erosion (Electric arc). 3 Electrical potential. 4 Workpiece. In wire electrical discharge machining (WEDM), also known as wire-cut EDM and wire cutting, [30] a thin single-strand metal wire, usually brass, is fed through the workpiece, submerged in a tank of dielectric fluid, typically ...

  7. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    The CO 2 laser is suited for cutting, boring, and engraving. The neodymium (Nd) and neodymium yttrium-aluminium-garnet lasers are identical in style and differ only in the application. Nd is used for boring and where high energy but low repetition are required. The Nd:YAG laser is used where very high power is needed and for boring and engraving.

  8. Photoengraving - Wikipedia

    en.wikipedia.org/wiki/Photoengraving

    A print made in 1907 from a photoengraved plate. It reproduces a sketch of Parga's castle made by Ludwig Salvator.. Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that protects some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas of ...

  9. Chemical milling - Wikipedia

    en.wikipedia.org/wiki/Chemical_milling

    A high-purity (≥99.9998%) aluminium bar that has been etched to reveal the component crystallites. Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape.
