Experimental Analysis & Optimization of Cylindirical Grinding Process Parameters on Surface Roughness of En15AM Steel

As per the modern Industrial requirements, higher surface finish mechanical components and mating parts with\ud close limits and tolerances, is one of the most important requirement. Abrasive machining processes are\ud generally the last operations performed on manufactured products for higher surface finishing and for fine or\ud small scale material removal. Higher surface finish and high rate of removal can be obtained if a large number of\ud grains act together. This is accomplished by using bonded abrasives as in grinding wheel or by modern\ud machining processes. In the present study, Taguchi method or Design of experiments has been used to optimize\ud the effect of cylindrical grinding parameters such as wheel speed (rpm), work speed, feed (mm/min.), depth of\ud cut and cutting fluid on the surface roughness of EN15AM steel. Ground surface roughness measurements were\ud carried out by Talysurf surface roughness tester. EN15AM steel has several industrial applications in\ud manufacturing of engine shafts, connecting rods, spindles, studs, bolt, screws etc. The results indicated that\ud grinding wheel speed, work piece speed, table feed rate and depth of cut were the significant factors for the\ud surface roughness and material removal rate. Surface roughness is minimum at 2000 r.p.m. of grinding wheel\ud speed , work piece speed 80 rpm, feed rate 275 mm/min. and 0.06 mm depth of cut
