Abstract
ABSTRACT In the context of the surface texture of the tool, turning process performance is sensitively affected by the surface texture geometry, design, and working environment. Therefore, present work focused on the fabrication of new texture design tools (an amalgamation of linear microgrooves and circular pit holes) and machinability evaluation of so developed tools in turning of AISI 304 material under dry and conventional cutting environment, respectively. Machinability measures considered in the work are cutting zone temperature (T), average surface roughness (Ra), and tool wear (Vb). Results indicated that the machinability of AISI 304 was significantly improved with the hybrid tools under conventional cooling compared to dry cutting conditions, respectively. Further, Scanning Electron Microscope (SEM) analysis revealed that adhesion wear is identified as the major tool wear mechanism in hybrid tools under both cutting environments. Furthermore, observed few surface defects in machined samples under conventional cooling conditions, respectively.
