Abstract

Surface treatment is an important aspect of all manufacturing processes to impart special physical and mechanical properties. Deep cold rolling (DCR) process is a post-machining operation in which the surface irregularities of workpiece are compressed by the application of a ball, which produces a smooth compact surface and simultaneously induces compressive residual stress. This paper describes a systematic methodology for empirical modelling and optimization of the DCR process parameters. The design of DCR parameters is based on response surface methodology, which integrates a design of experiment, regression modelling technique for fitting a model to experimental data. Central composite design has been employed to develop a second-order surface roughness model. Response surface methodology was employed to optimize the set of parameters to ensure a minimum surface roughness. The optimum conditions found by RSM for the deep cold rolling process are, rolling force of 507.7N, ball diameter of 10mm, initial roughness of 4.84μm and 3 number of tool passes
