Optimization of Roller Burnishing Process Parameters for High Strength En19 Alloy Steel

摘要

The present experimental investigation focuses on effect of various parameters and optimization of burnishing processes on surface finish and surface Harding of EN19 material during burnishing operation. Burnishing is a chip less finishing method which employs a rolling tool pressed against the work piece for achieving plastic deformation of the surface layer. Design of experiments (DOE) methodology was used for the optimization purpose. L'27 orthogonal array (three factors at three levels) was chosen. The parameters considered for the present study were speed, force and feed. By of the Taguchi methodology optimum machining parameters obtained which gives better surface finish and Hardness.
