The drawing forces during wire and tube drawing can be reduced by ultrasonically oscillating dies. A major problem of conventional wire and tube drawing is to introduce high forces into the forming area. Compared to conventional wire and tube drawing, the forming process limits can be extended by superimposing ultrasonic waves due to decreasing drawing forces. Different techniques can be used to exite the die. One possibility is the variation of the vibration mode. In tube and wire drawing, the dies are usually exited longitudinally. If the vibration direction is parallel to the drawing direction, the main influence will be on the friction between workpiece and die. The Institute for Metal Forming Technology of the University of Stuttgart, Germany started a project to investigate the effect of ultrasonic waves on the tribology and on the the formability of the workpiece. The objective of this investigation is to separate the ultrasonic effect on the surface from the volume effects.
