Area of overlap in hammer peening operations defines the resulting percentage overlap of surface. It thus is one of the main factors to control in order to reach defined treatment intensities, surface textures or other surface layer states. In this work, three different techniques to calculate overlap are compared and the results for two cases discussed. One case concerns a classic hammer peening process done using a spherical hammer head. The second case concerns the more complex indentation shape of a cutting tool.
