The final accuracy of the parts formed using single point incremental forming greatly depends on the mechanical properties of the material to be formed and residual stress formation. In this paper, an X-ray diffraction technique is used to study the distribution of the residual stress along the generating line of the conical drawpiece. As a test material DC04steel sheet with a thickness of 0.8 mm was used. The basic mechanical properties of the DC04 sheet metal were determined in the uniaxial tensile test according to the EN ISO 6892-1:2016. It was found that the maximum amount of the residual stress existed in a point located in the midway between a base and a truncation of the drawpiece. In the outer surface of the drawpiece the orange peel defect associated with a rough surface appearance after SPIF a drawpiece is observed. In contrast, the inner surface of component is characterized by linear grooves associated with the interaction of tool tip with the sheet surface. This defect is mainly influenced by vertical step size.
