They can be listed as: 1. Material deposition technologies, such as casting and sintering, or the new "rapid manufacturing" techniques developed rapidly in the last ten years. 2. Joining techniques, in which riveting, friction stir welding (FSW), welding and assembly are classified. 3. Forming, where hot working techniques like forging and cold working techniques such as forming, spinning and involute splines production are placed. 4. Material separation, including shearing, nibbling, punching, cutting by laser and cutting by high pressure water or abrasive waterjet (AWJ). 5.
