For this reason, it is important to increase the surface quality of the material and reduce the tool consumption. In the present work, the shallow and deep cryogenically treated performance of cubic boron nitride (CBN) inserts in terms of surface roughness, tool wear, thrust force and chip formation under dry cutting conditions for finish turning of Hastelloy C22. The effect of CBN tools on cutting force, surface roughness, hardness and chip morphology was investigated by applying shallow and deep cryogenic treatment. With the surface roughness values obtained with the deep cryogenic-treated tools (DCT) tool, 137.1% and 73.8% improvements were achieved compared to the RT (Reference tools) and Shallow cryogenic-treated tools (SCT) tools, respectively. DCT and SCT tool were 31.58% and 5.5% lower than the cutting forces obtained with the RT cutting tools, respectively. According to ANOVA analysis, the most effective parameter affecting the surface roughness was determined as the feed with a 67.8% contribution.en10.1007/s11665-021-05453-5info:eu-repo/semantics/closedAccessCBN insertcryogenic treatmentsurface roughnesscutting forceArticle302128012882-s2.0-85099542580WOS:000608943900003Q2Q4
