Fast determination of parameters describing manufacturing imperfections and operation wear of nanoindenter tips

► In nanoindentation the exact knowledge of the indenter tip geometry is pivotal. ► Tip geometry changes during the indenter operation time, due to diamond wear. ► A fast method for estimating diamond indenters' tip geometry was developed. ► This method is based on nanoindentations and FEM-calculations of Martens hardness. ► A software package “TIDE” (TΙp Deviations Estimation) has been developed.
