Abstract
The surface integrity of the material is the predominant necessity of a component to perform efficiently in varying working conditions. To improve the surface integrity of the workpiece secondary finishing processes are being performed. This work attempts to propose a realistic cryogenic slide burnishing condition for improvement of the surface integrity. The slide burnishing was performed by a novel slide burnishing tool on 17–4 precipitation hardenable stainless steel. The experiment was designed based on a central composite design. Initially, the effect of control parameters on the output response was examined by experimental analysis based on the design of experiment. Analysis of variance was used to analyze the influence of the variables on the performance indices. The regression technique was used to develop an empirical model. Optimization of process parameters for finding minimum surface roughness and maximum surface hardness was achieved by a multi-objective genetic algorithm. The optimized solutions were validated by performing confirmation experiments.

The surface properties and dimensional precision of the components are the two most crucial factors which are considered seriously in modern manufacturing industries
As the slide burnishing process is carried out, the diamond tip slides over the workpiece, and the mirror finish of the surface can be attained with a careful assortment of the process parameters
If the feed was increased further way beyond this limit a sudden increase in the surface roughness has been noticed. It is because the gap amongst the successive traces of the tool tip is small at lower feed and at higher feed more gap will be available among the successive traces of the tool which causes a sudden increase in the surface roughness of the specimen [29, 30]
Summary
The surface properties and dimensional precision of the components are the two most crucial factors which are considered seriously in modern manufacturing industries. The slide burnishing process is one of the recent developments in the area of burnishing which has been utilized by most of the production industries to increase the surface integrity properties of the material. Diamond has been used at the tip of the stem of the tool which will deform the material. As the slide burnishing process is carried out, the diamond tip slides over the workpiece, and the mirror finish of the surface can be attained with a careful assortment of the process parameters. The functional properties of the material can be improved after performing a slide burnishing operation using LN2 as the coolant, and it has to be directed at the slide burnishing zone
