Electron beam cutting Glossary S Bibliography Biographical Sketches Summary 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, c
