The process induced residual stress led to a significant part distortion of the machined part with a maximum of 0.510 mm on the measured profile. The comparison of machined and simulated distortions can be seen in Fig. 6. convert photo to drawing illustrator Web[1], the residual stresses are normally associated with pure bending stresses [2]. Although some residual stresses exist in the arterial longitudinal direction [3] and [4], we will assume that only one longitudinal cut is sufficient to release almost all residual stresses [5] and [6]. In this work, the artery is treated as single-layered structure.
