Abstract: The tool effective speed (tool rotational speed and feed rate) play an important role in formability of a single point incremental forming process. The interrupt material flow of that process allowed the part wall thinner than the continuous flow of a conventional forming process. This research object was to study the effective speed, which affected to formability of DIN 1.0037 steel (St 37-2 steel). The different tool rotational speed 100 and 1000 rpm, and the different feed rate 300 and 3000 mm/min were selected as the process parameters to forming the 100 mm half sphere or dome shell by the 10 mm ball end. The result shows, that the tool rotational speed and the feed rate are affected to SPIF formability of sheet metal, the tool rotational speed had a more effect to formability, increased tool rotational speed, decreased formability by mean of increased roughness and wear of specimen. The tool feed rate had a little effect to formability, increased feed rate, decreased formability by lowering depth of specimen.
