Abstract: The study deals with the mechanism of smoothing surface creation by tip-type burnishing process. The diamond-tip type tool can burnish hardened materials. However, diamond chip burnishing tools are not yet generally used because the mechanism of the process was not established. It is considered that the height of this is the dimensional change amount caused by burnishing when the solid part is pressed and the void is filled in the burnishing process. Experiments of changing the indentation depth by the use of A7075 as workpiece material were conducted. The objective of this study is to clarify the relationship between spring back effect and plastic deformation. From the experimental result, in the case of pushing, the depth of pushing is equal to the depth of the lowest level of cutting surface burnishing tip; decompression depth is about 70% to 80% of indentation depth by spring back.
