Abstract
In this work, the effect of different viscosities of an oil in magnetic abrasive finishing process (MAF) is analysed. The material specifically chosen for experimentation is Brass alloy (CuZn). The surface of the Brass alloy in this study was exposed to different tests during which key parameters were altered. In order to keep the objectives of this study aligned the list of parameters was limited to six. The six parameters were: Viscosity;Quantity of the powder (doze);Distance between pole and the work piece;Pole diameter;Pole rotational speed and Current. The choice of parameters was based on the Taguchi orthogonal array (OA), with three levels of variance for each parameter. To determine the signal to noise ratio (S/N) and to obtain the optimum condition of micro hardness, Hv, the statistical software (MINITAB 17) was used. The experimentation was repeated with and without oil to identify the significant parameters affecting the micro hardness level (Hv).
