Experimental Evaluation of Grinding Process Parameters on Surface Finish

In relation to the surface grinding of mild steel samples, the present experimental work successfully analyzed the effect of grinding process parameters on surface finishing. From the study, it is evident that the surface roughness and grinding efficiency depend significantly on the wheel speed, feed rate, and depth of cut. From the experiment, it was found that an increase in wheel speed contributed to better abrasive contact and thinner chips, thereby enhancing the surface finish. On the other hand, high feed rate and depth of cut caused greater surface roughness because of the presence of high grinding force, vibration, and heat generation. The highest grinding efficiency was achieved for all test cases at a wheel speed of 1800 rpm, a feed rate of 150 mm/min, and a depth of cut of 0.01 mm, providing the lowest surface roughness value, which is 0.45 µm.The research proves that good surface finish, dimensional accuracy, reduced heat distortion, and machining efficiency are all based on the proper setting of the grinding parameters. The findings of the research can be applied to boost productivity and quality of products in the automobile, aerospace, tool manufacturing, and precision engineering industries.
