Effect of Cutting Insert Type on Surface Roughness of Hardened AISI 420 Stainless Steel

Abstract

AISI 420 stainless steel is one of the alloys that can be used in various applications due to its malleability, high strength, and weldability. In this study, the effects of cutting parameters (feed rate, depth of cut, and cutting speed) on the surface roughness were investigated during the turning of AISI 420 under dry test conditions using coated carbide and ceramic cutting inserts. Response surface methodology, analysis of variance, and statistical methods of the main effect plot were applied to investigate the effects of input parameters on response values. The results of this study showed that feed rate followed by the depth of cut had the most significant effect on output parameters. According to the experimental data, as the feed rate and depth of cut increase, the surface roughness increases.

“…The global growth of the manufacturing industry and increasing environmentally conscious consumer preferences compel researchers and production plants to seek alternatives to traditional cutting fluids [13]- [15]. Over the past decade, various techniques, such as wet machining, minimum quantity lubricants (MQL), cryogenic cooling, and solid lubricant-assisted machining, have emerged as environmentally friendly solutions [16].…”
