Examine the Influence of Novel Cryogenic Machining on Tool wear in Milling of Super Duplex Stainless Steel Alloy

Mandala Ajay Naidu and B. Navin Kumar

Abstract

The primary focus of this work is to study the impact of a novel cryogenic machining technique of tool flank wear in machining of super-duplex stainless steel and compare the surface finish of the samples with the machined surface performed by dry machining process. Two set of groups were taken for the study, i.e. control group (Dry machining) and the study group (Machining with cryogenic machining technique). The number of samples is calculated using the sample calculator. Twenty samples were taken for each group. In the control group, the machining operation is carried out on Super-Duplex Stainless Steel without any kind of lubrication. In the study group using a novel cryogenic machining technique, the compressed lubricant is sprayed to the machining area. The flank wear of the cutting tool of each group is measured by microscopic images. The influence of the novel cryogenic machining technique on the tool wear of the inserts is studied. The number of the samples was calculated by keeping the alpha value 0.05 and G-power as 80%. The flank wear of the cutting tool of the samples from novel cryogenic machining is lesser than the samples obtained from the dry machining operation. It was noticed that there is a 65% reduction in tool wear when the Cryogenic machining technique has been implemented over dry machining.
