-Abstract
This study deals with a new approach to understand the finishing of Ti-6Al-4V alloy by chemical assisted
magnetic abrasive finishing (CMAF) process. In the present work a CMAF setup is design and developed. In this
process, material is removed by chemical dissolution as well as magnetic abrasive action on workpiece without applying
any cutting forces on cutting zone. The present study also develops optimization for CMAF process of Ti-6Al-4V alloy
using Taguchi method. Various parameters such as rotational speed from 60 to 180 rpm, concentration of abrasive from
10 to 20 %wt, and working gap from 2 to 6 mm to be considered for analyzing the chemical assisted magnetic abrasive
finishing (CMAF) performance criteria e.g. percentage of surface roughness. From the analysis of variance of results, it
is conclude that rotational speed has probability value of 0.027, which means it is most significant parameters of CMAF.
For lower Surface roughness, the optimum parameters for chemical assisted magnetic abrasive finishing (CMAF) are
rotational speed i.e. 180 rpm, concentration of abrasive is 15 %wt, and working gap is 4mm
