Sažetak
Most materials, including metals, will burn. A number of cutting processes exploit this fact by bringing about the rapid oxidation of material, to form a kerf, or cut. Thermal cutting in this manner offers many advantages over traditional subtractive machining methods such as sawing. As the process does not require the physical contact of a tool with the work surface, cutting forces are almost negligible, rates of material removal are faster and the mechanics of machine design are simplified. Depending on the source of heat input, there are various processes which can be divided into oxygen, arc and beam cutting processes. Oxygen cutting describes a group of cutting processes used to sever or remove metals by high-temperature exothermic reaction of oxygen with the base metal. In arc cutting, the metal is simply melted by the intense heat of the arc and is then blown away by the force of arc itself or by other gases (such as air or shielded gases). Beam cutting utilizes a beam of light as a heat source. The advantages of these non-contact cutting processes include not having to rely on perishable cutting tools to shape parts or elaborate work holding methods and systems to clamp parts. These processes do, however, use consumable items such as torch tips, gases, and abrasive materials.
