Performance evaluation of textured carbide tools under environment-friendly minimum quantity lubrication turning strategies

Abstract

Present investigation is focused to study the impact of different lubricating environments using pure canola oil and graphene mixed in canola oil, on the performance of uncoated carbide textured tools in minimum quantity lubrication (MQL) turning of AISI 4340 hardened steel. The influence of using twin jet and single jet was also studied under MQL. The turning performance was evaluated in terms of flank wear (VB max), cutting forces, cutting temperature, and chip morphology. The results showed that MQL mist supplied simultaneously on rake and flank face of the textured tool by twin-jet nozzle performed better than MQL mist supplied on the rake face of textured tool by the single-jet nozzle. Out of all the tested lubricating environments, best tool life was achieved with nanoparticle minimum quantity lubrication (NMQL) using the twin jet followed by only oil using twin jet as compared to all other conditions tested in this study. The outcome of the study illustrates that MQL mist of graphene which is mixed in canola oil on a textured tool with the twin-jet nozzle can be successfully applied for finish turning of hardened steel.

Optimization of machining parameters under MQL turning of Ti-6Al-4V alloy with textured tool using multi-attribute decision-making methods

“…10 ns) was used. The diameters(f ) of dimples were 80 mm, 50 mm deep at a distance of 150 mm from the main cutting edge and the center distance between each dimple is 150 mm, as indicated in Figure 1 (Sharma and Pandey, 2017;Singh et al, 2019a). The inserts were then cleaned with a 20-minute ultrasonic bath in acetone solution.…”

A Comprehensive Review on AISI 4340 Hardened Steel: Emphasis on Industry Implemented Machining Settings, Implications, and Statistical Analysis

“…Usually, tool wear influences directly the quality of the finished part and manufacturing costs; however, wear is an inevitable phenomenon. The influence of various lubricating surroundings by pure canola oil and graphene mixed in canola oil, on the output characteristics of textured carbide uncoated tools in MQL based AISI 4340 turning has been studied effectively [72].…”

Performance of textured tool in turning of Ti–6Al–4V alloy: numerical analysis and experimental validation

“…Other researchers [20][21][22] also studied the enhancement in machinability in terms of drill life using grooving or texturing on the drill bit. Singh et al [23] investigated the textured carbide tool under the MQL condition. It is revealed that the texturing on the carbide tool reduces chip curl diameter and improves tool life compared to dry cutting.…”
