Machining performance investigation on 17-4PH steel material with innovative textured tools

The machinability characteristics during turning process are noticeably influenced by the texture design particularly single pattern or dual pattern about surface textured tools. In this context, novel dual pattern textured tools were developed in the present work and compared its machinability performance with conventional tools respectively in tuning of 17-4PH steel under wet cooling conditions. Dual pattern textured tools consists of continuous microgrooves which are combination of parallel and perpendicular to the chip flow direction and also, have microgrooves parallel to principal cutting edge and secondary cutting-edge to enhance. In this work, investigation was done at different cutting velocity. Cutting temperature (T), surface roughness (Ra), and tool flank wear (Vb) were shown to be significantly decreased by hybrid textured tools compared to conventional tools, with maximum values of 26%, 28%, and 21%, respectively. Further, developed textured tools found with low adhesion and abrasion wear when compared to conventional tool. Moreover, interaction effect of input process variables on outputs was studied via interaction plots. From results it was retrieved that hybrid textured tools served as coolant storages sites to supply coolant to the cutting zone effectively.
