“…Thesurface roughness value in cryogenic cooling method was found to be more as compared to other modes at all cutting speeds. These results were consistent with the results obtained by Ahmed et al [32] under cryogenic cooling condition. The increased workpiece hardness under cryogenic condition could be one of the possible reasons of increased surface roughness.…”

In order to eradicate the use of mineral based cutting fluid, the machining of Ni-Cr-Co based Nimonic 90 alloy was conducted using environment friendly sustainable techniques. In this work, uncoated tungsten carbide inserts were employed for the machining under dry (untreated and cryogenically treated), MQL and cryogenic cutting modes. The influence of all these techniques was examined by considering tool wear, surface finish, chip contact length, chip thickness and chip morphology. It was found that the cryogenically treated tools outperformed the untreated tools at 40 m/min. At cutting speed of 80 m/min, MQL and direct cooling with liquid nitrogen brought down the flank wear by 50% in comparison to dry machining. Similarly at higher cutting speed MQL and cryogenic cooling techniques provided the significant improvement in terms of nose wear, crater wear area and chip thickness value. However, both dry and MQL modes outperformed the cryogenic cooling machining in terms of surface roughness value at all the cutting speeds. Overall cryo treated tools was able to provide satisfactory results at lower speed (40 m/min). Whereas both MQL and cryogenic cooling method provided the significantly improved results at higher cutting speeds (60 m/min and 80 m/min) over dry machining.

“…Cryogenic cooling by liquid nitrogen jets provided reduction in average chip-tool interface temperature, high reduction in flank wear, better surface finish and dimensional accuracy as compared to dry machining of AISI 1060, AISI 1040, E4340C, AISI 4140 and AISI 4037 steels [10][11][12][13]. Cryogenic machining by liquid nitrogen with the help of modified tool holder provided longer tool life and more wear resistance compared to dry machining [14].…”

“…Their results indicated a substantial reduction in grinding forces with cryogenic cooling. Cryogenic machining using liquid nitrogen with the help of a modified tool holder provided longer tool life and more wear resistance, compared to dry machining (Ahmed et al 2007). Kalyan Kumar and Choudhury (2008) presented an experimental investigation of tool wear and cutting force in cryogenic machining.…”

This paper presents a novel lubrication method for milling processes that employs cooling system-assisted minimum quantity lubrication (CSMQL) using a thermoelectric cooling system. The CSMQL method improves the cooling effect in the cutting area and enhances processing quality, in addition to reducing energy consumption. Four different coolant strategies including CSMQL, dry, minimum quantity lubrication (MQL), and wet methods were compared in processing mill die steel (SKD11), which is widely used in industry. Different aspects of the milling performance (e.g. surface roughness, morphology, milling temperature, and milling forces) were investigated using these coolant strategies. The experimental results show that not only is the surface roughness of steel milled using CSMQL better than that of steel milled using dry and MQL methods, but CSMQL also produces fewer tool marks on the workpiece surface. In addition, it was found from observations of chip color that using the CSMQL method reduced the cutting temperature by 27% and the cutting force by 22%, compared with dry machining. In summary, the use of CSMQL can not only improve the surface roughness and reduce the cutting force and cutting temperature, but also promote processing quality. This study will help researchers develop more efficient cooling strategies in the future.
