AbstractIn an experimental analysis study, a mix of burnishing parameters was varied to obtain the optimum roller conditions that produce superlative surface smoothness and hardness. The analysis was undertaken on roller burnished mild steel and aluminium using a purpose designed and manufactured tool. The effects of burnishing parameters on both the surface roughness and hardness of mild steel and aluminium work pieces materials were observed and analysed. The parameters included; burnishing speed, feed, force and the number of the tool passes.The results indicated that,depending on the work piece material, surface finishand hardness improvements of around (75%) and (50%) respectively were obtainable at optimumvalues of the mentioned parameters.
