Effect of burnishing force and feed on the depth of the surface hardened layer in plane surface ball burnishing

Abstract EN

In an experimental analysis study, a blend of burnishing parameters was varied to obtain their optimum values to produce the finest surface integrity in plane surface burnishing process.

The physical depth of the micro hardened surface layer was also evaluated at the obtained optimum values of the parameters.

The analysis was undertaken on ball burnished plane surface, mild carbon steel M1044, using a milling machine and a purpose designed and manufactured burnishing tool.

The effects of burnishing feed and force on both surface smoothness and hardness together and on the depth of the hardened surface layer of the work pieces material were observed and investigated.

The results indicated that plane burnished surface finish and hardness improvements of around (89 %) and (70 %) respectively were obtainable at the optimum values of the mentioned parameters.

Around 35 μm physical depth of the hardened surface layer was the result at the obtained optimum burnishing force and feed values of about 7.8Kgf and 107 mm/min respectively.
