Comparing CNC Turning of 2205 Duplex Stainless Steel Using Novel Textured Tool with Untextured Tool for Reducing Flank Wear Under Nano Minimum Quantity Lubrication Condition

S. Jawahar and M. Thiyagu

Abstract

The principal objective of this study is to conduct a comparative analysis between newly developed textured carbide tool inserts and their untextured inserts in the CNC turning of 2205 duplex stainless steel. This analysis is focused on mitigating flank wear while operating under nano-minimum quantity lubrication conditions. Surface texturing is an environmentally sustainable manufacturing technique that offers an appealing approach to modifying the surface topography of cutting tools, particularly at the rake face. This alteration aims to enhance the wettability of cutting fluid at the cutting edge, facilitating more efficient machining processes. A linear groove texture pattern is engraved on the tool surface using a femtosecond laser technique. A Jobber XL CNC turner used for turning operations on 2205 duplex stainless steel with textured tool inserts and was compared with untextured tool inserts in terms of flank wear. Box benhen design used for conducting experiments. The sample size of each group is 20; there are two groups; the total sample size is 40. The experimental results show a flank wear of 0.252 mm for single-textured tools and 0.187 mm for untextured tools in turning 2205 duplex stainless steel rod. With the study limits, the proposed single linear groove textured tool insert showed a reduction in flank wear (16.45%) compared to the untextured carbide tool inserts.
