Abstract
Burnishing is a cold working process that employs plastic deformation of a suface layer in order to improve surface characteristics such as surface finish and microhardness of the workpiece.. Machined surfaces by conventional manufacturing processes such as turning and milling have inherent irregularities and defects like tool marks and scratches that cause energy dissipation (friction) and surface damage (wear). Burnishing is a kind of chip-less processing which improves the surface integrity of machined components. A new burnishing tool is introduced in this investigation which enables double ball burnishing process along with turning without releasing the workpiece. Effect of burnishing parameters namely burnishing feed, burnishing speed, and number of passes on final surface texture (roughness and roundness) were demonstrated. Burnishing results showed significant effectiveness of the newly developed burnishing tool in the process. For the aluminium alloys in this investigation, the best results of surface finish and surface hardness with saving in energy were obtained with double ball burnishing. The results of combined turning and double ball burnishing were better than that of performing individually.
Keywords- Ball burnishing, turning surface roughness, micro hardness
