25 th September, Laser cut and Stencils, Fonts and Images Researching laser cutting We will be following…. - The design process - Technical process - Materials aspect The laser cutting process - Laser cutting is a precise method of cutting a design from a given material using a CAD file to guide it - 3 main types of lasers are used in the industry, C02 lasers, Nd and Nd-YAG - C02 machines involve firing a laser which cuts by melting, burning or vaporizing the material. This achieves a fine level of cutting detail on a wide variety of materials. C02 lasers can’t cut metals and hard materials but they can engrave them. Laser head and tolerance - The beam is emitted from the ‘laser tube’ and is reflected by mirrors into the ‘laser head’ - Within the ‘laser head’ is a lens that finely focuses the beam onto the material surface for cutting or engraving - The kerf refers
