Abstract
A common machining technique used in the industrial sector to shape and finish workpieces composed of different materials, including steel alloys, is turning. This study investigates the influence of cutting speed and feed rate on material removal rates (MRR) for several steel alloys commonly used in engineering applications. For machining operations to be optimized in order to increase productivity and lower production costs, it is essential to understand how these characteristics affect MRR. Using a lathe machine and carbide cutting tools, a series of turning tests were performed on several steel alloys, including carbon steel, stainless steel, and tool steel. MRR was calculated as a response variable, and the cutting speed and feed rate were systematically changed within a predetermined range. To determine the effect of cutting speed and feed rate on MRR, the experimental data were statistically evaluated, using analysis of variance (ANOVA). According to the research, the scraped metal rate rose together with the feed rate and cutting speed. The highest scrapped metal rate was 180 mm/min at 168.13 m/min cutting speed and 1.12 mm/rev feed rate. With the feed rate and cutting speed increasing, so did the amount of metal that was wasted. 56 mm3 of metal was discarded at its highest volume at a cutting speed of 168.13 m/min and 1.12 mm/rev. The amount of metal that is rejected rises with feed rate and carbon content, with 56 mm3 at 168.13 m/min and ST3 metal being the highest value. With feed rate and carbon content, the needed energy likewise rises, with the highest value being 190 J at 168.13 m/min and ST3 metal.
