Enhancing machining efficiency of AISI 316 using novel microgroove textured tools with MQL cooling

High tool wear and poor surface quality significantly lead to high production cost in a metal cutting operation. Additionally, excessive usage of chemically contaminated coolants during machining negatively affects the operator health. To address these issues, novel surface textured tools were fabricated in the present work and assessed the machining performance of developed tools while cutting AISI 316 stainless steel material under Minimum Quantity Lubrication (MQL) by varying cutting inputs such as cutting velocity (v), feed rate (f), and depth of cut (ap). Notably, parallel grooved textured tools (PT) with MQL have shown remarkable improvements in machining performance compared to untextured tool (NT). The PT tools reduced the cutting temperature (Ct), rake wear (Wr), surface roughness (Ra), and cutting force (Fc) to maximum of 27%, 22%, 18%, and 30%, respectively, when compared to NT tool. These findings highlight the effectiveness of the proposed approach in improving machining efficiency and sustainability.
