Abstract
Machining of bearing steel material such as AISI 52100 steel is one of the challenging fields in the metal cutting industries due to the high hardness which results in low productivity and high manufacturing cost. To overcome these issues, in the present work, the new cooling approach was proposed by combining two sustainable machining techniques, that is, the usage of surface textured tools under the minimum quantity lubrication (MQL) environment. In the experimental investigation, three types of cutting tools were considered, among that two were surface texture tools, namely surface texture grooves 45° inclined to the main cutting edge tool and circular perforated holes tool, and third is a nontexture tool. Taguchi analysis was carried out to study the effect of different surface texture tools and process parameters on turning performance during machining of AISI 52100 steel under MQL cooling condition. From the Taguchi analysis, optimum cutting conditions were determined for obtaining the low surface roughness and tool flank wear, respectively. Also, it was concluded that surface texture grooves 45° inclined to the main cutting edge tool type significantly reduced the surface roughness and tool flank wear, respectively.
