The paper deals with an analysis of a hole flanging technology, especially with the influence of an initial hole production process on an ability of material to achieve the required expansion in the application for automotive industry, i.e.radius rod production. S420MC steel sheet with a thickness of 4 mm is used as a material for the production of flanged parts. In this case, the possibility of improving limits in hole flanging by shaving technology is investigated. Therefore, holes made by conventional punching, shaving and laser cutting are investigated, for further comparison, using so-called hole expanding test. Subsequently, test results are compared with the prediction based on numerical simulation model in PAM-Stamp software.
