Optimization of process parameter for surface finishing in abrasive flow finishing process

274 Optimization of process parameter for surface finishing in abrasive flow finishing process Ravi Gupta (M.E) Asst. Prof.(Lovely Professional University) [email protected] , Abstract-Abrasive flow finishing is a non-conventional finishing process that is used for finishing of work piece which are difficult to finish by conventional method i.e. by honing, lapping and other machining operations. It is used for polishing, deburring, removing recast layer of component and for cleaning of surfaces having complex shape and size of geometrical components. Abrasive flow finishing process polishes the surface by forcing the abrasive medium inside the work piece through the restricted area. One of the limitations of this process is that it is time consuming process and low material removal rate. To overcome these limitations, a structure has been developed. In this setup, centrifugal force has been generated by using a tool rod inside the hollow work piece to which rpm was provided. The abrasive mesh size, abrasive concentration, number of cycle, extrusion pressure, rotational speed of CFG rod, diameter of tool rod and shape of tool rod are the some important process parameter which affects the surface quality. In this research paper, the role of abrasive mesh size, extrusion pressure, abrasive concentration and rotational speed has been discussed on Gun metal as material of work piece. For experimentation design, taguchi approach L9 orthogonal array has been used and for analysis of result, ANOVA has been performed.
