Abstract

The surface roughness of machined surfaces, for example, plays a crucial role in the production of the final part or product. As a result, selecting the machining parameters and cutting tool geometry during machining is critical in determining tool wear progression as well as obtaining lower surface roughness or high surface quality of the surface after machining. The goal of this article is to optimize the cutting tool's cutting-edge radius (CER) of uncoated carbide and width of cut during the machining of DAC 55 steel. A continuous cutting speed of 2800 RPM and a feed rate of 350 mm/min were used to side mill DAC 55 steel. The influence of both factors on surface roughness and tool wear was studied using width of cut 0.1, 0.6, and 1.2 mm with CER of 10, 20, and 30 µm. The Full Factorial approach was used to assess the impact of combining cutting parameters. According to the findings, the width of cut has the greatest impact on enhancing surface quality compared to CER. It was discovered that using 30 µm CER and 0.1 mm width of cut resulted in the best surface finish quality. In terms of cutting tool wear, it was discovered that a cutting tool edge radius of 30 µm and width of cut of 0.1 mm experienced less wear when reaching a distance of 4400 mm.
