Cutting materials is the first stage of manufacturing products. The quality of this operation determines the properties of the cut surface, which influence the further processing of the product. The paper considers the most important numerical cutting methods: gas, plasma, laser, abrasive water jet cutting, and electrical discharge machining. The basic parameters affecting the quality of the cut surface, related to the processing technology and the type of material being cut, were determined.Cutting is a technological process most often used in the processing of metal materials, consisting of creating such a state of stress in the desired location that a fracture of the processed material occurs there, usually preceded by plastic deformation. The essence of cutting is overcoming the cohesion of the material. This process requires the input of appropriate energy. (…)
