Abstract. Fatigue strength of a part formed by incremental sheet forming (ISF) can potentially be improved by reducing the extent of damage, void area fraction, through control of process parameters. This study aimed to clarify the damage induced by ISF and the effect of process parameters, particularly depth increment during ISF, on the void area fraction. Scanning electron microscopy observation and quantification, trained by a neural network model, found two results: the void area fraction on the tool side was not less than three times smaller than on the rear side of the formed parts, and the fraction decreased with the increase in depth increment.
