Abstract	The cut-edge condition has an important influence on the formability capacity of high-strength steel (HSS) automotive structures. XF350 and DP600 under examination were observed to display a decreased level of formability in the surface regions because mechanical punched edge hole-flanging capacity is dependent on ductility and the surface quality of the cut-edge produced. Formability was observed to be highly dependent not purely based on the properties of the steel but also the cut-edge properties. Hole expansion capacity (HEC)-forming experiments were performed on flat circular plates with mechanical and laser-cut holes to investigate the fracture and forming limits of HSS. The HEC properties of the cut-edges were determined using mechanical and laser-cutting processes using various cutting process parameters in which certain edge types displayed decreases in edge ductility. It was found that, by altering the processing parameters during the cutting process, the edge quality can be improved, and this has a positive effect on the formability capacity of steel components.
