Abstract

The difficulty in manufacturing Rockwell diamond indenters to the required geometric specifications has resulted in most commercially manufactured indenters to vary in shape from one indenter to another. This difference in shape is thought to be a major contributor to Rockwell hardness measurement uncertainty. In this paper, finite element analysis (FEA) is used to simulate the hardness measurement process. The model has made it possible to predict the extent to which a diamond indenter's tip radius, cone angle and form error influences the hardness measurement value. These predictions have been verified by experimental measurements.
