FLAME CUTTING (FOR METALS)
Flame cutting (for metals) (fr: Découpe à la flamme – pour métaux): A process used for cutting and shaping metals; also know by many more names like oxy-fuel cutting, oxygen burning, steel burning and other terms. Flame Cutting is Thermo-Chemical process that requires an intense source of heat and pure oxygen (minimum purity of 99.5%). The cut occurs by using a torch to heat the metal to its auto-ignition temperature, and then a stream of oxygen is directed on the metal, burning it into metal oxide that exits the kerf as slag.
FOLDING (OF METAL SHEETS)
Folding (of metal sheets) (fr: Pliage – de tôles métalliques): A type of metal bending technique in which clamping beams hold the longer side of the sheet; the beam rises and folds the sheet, enabling the forming of parts with positive and negative bend angles. In metal folding, the bend angle is influenced by factors like: folding angle of the beam, tool geometry and material properties. Folding allows the working of large sheets, facilitating the automation of the process.
