Experimental investigation on surface characteristics of copper by roller burnishing process

Surface finish will enhance the life of a product and it ensures durability and reliability. Roller burnishing process is a chip less machining process to finish the surface smoothly. It employs a rolling tool which rolls on the surface with high pressure to achieve the plastic deformation. In this process material will be displaced as a cold flow from peak to valley. It improves the surface texture like a mirror finish and produced hardness and toughness. In this paper an experimental study is presented which is carried out by doing burnishing process with hardened roller on a copper sheet. This surface hardness and surface structure was examined by varying burnishing parameters. A micro structure is then depicted for the burnished work piece.
