Abstract. In-line adjustability of tools for high-volume forming processes could improve yield while reducing lubricant use. This work presents an improved design of an ironing punch with adjustable tool diameter and an experimental study of its performance. Experimental results are compared with numerical simulations conducted in LS-DYNA. Punch retraction force of the new design was 68-85% lower than that of a conventional punch, indicating a lower contact pressure and thus reduced tool wear. The wall thickness of the ironed cups was adjusted by about 25 µm.
