Performance evaluation of developed new textured tools during turning of AISI 321 material

ABSTRACT

Nowadays, productivity enhancement in machining operations in eco-friendly machining environment is a front-end requirement in the machining industries. In general, minimizing tool wear (V_b) and surface roughness (R_a) in machining processes can directly boost productivity. Therefore, the current effort attempts to improve productivity by regulating tool wear and surface roughness in an environmentally friendly machining environment. In this study, innovative textured tools (TT) were created, and the machinability performance of the produced tools was assessed under dry, conventional, and MQL conditions. According to the study’s findings, MQL cooling with TT considerably reduced the cutting temperature (T), V_b, and R_a to maximum values of 13%, 17%, and 29%, respectively, over untextured tools (UT). In addition, it was shown that MQL cooling considerably enhanced turning performance in both tools compared to without cooling and conventional cooling, respectively. Additionally, chip morphology research was done and showed promise using textured tools in MQL conditions as opposed to other machining settings.
