“…Literature studies showed that abrasive wear mechanism is responsible for the progressive flank wear. 67 In this particular study, element analysis showed this situation for the cutting tools used under dry environment. However, the entity of the LN 2 coolant or mist oil surpassed the thermal variations at the cutting zone which paves the way for keeping material integrity of tool and workpiece.…”

Armox 500T is a special type of armor steels possessing superior mechanical properties suitable for use in vehicles and buildings need for first priority protection. Since these products are large-scale, welding groove need to be created before joining which can be done by milling operations. This study aims to address this point by questioning the impact of clean environments namely dry, minimum quantity lubrication (MQL) and LN2 based cryogenic cooling on the machining performance measures during milling. The novelty of this paper is the investigation of the effects of different cutting environments on the milling performance of Armox 500T armor steel. The results from this study showed that cryogenic medium has an impressive impact on controlling the temperatures at tool-chip interface which directly reduces flank wear development. In addition, cryogenic and MQL-assisted machining is much better than dry environment in achieving improved surface properties, chip shape and energy consumptions. Cryogenic cooling seems as the best option for hard milling pursued by MQL and dry environments respectively from the sustainability and machinability point of view.

“…According to the principle of metal cutting, the cooling and lubrication effect of cutting area is the main factor affecting the tool life. In the process of machining, the cooling and lubrication effect of the cutting area is poor, which not only increases the surface temperature of the cutting tool and aggravates tool wear but also reduces the machining accuracy [ 2 ]. Therefore, it is very important to reduce cutting force, speed up cooling, reduce cutting heat, reduce friction coefficient on friction surface, and use cutting fluid reasonably.…”

In order to strengthen the thermal conductivity of green cutting fluid and the influence of nano-cutting fluid from new cutting and forming processes on heat transfer performance of mechanical engineering, a research method was proposed based on the influence of nano-cutting fluid from new cutting and forming processes on heat transfer performance of mechanical engineering. The dispersion stability, thermal conductivity, and viscosity characteristics of the nanofluid were studied, and the effects of acidification treatment time, type and concentration of carbon tube particles, surfactants, and testing conditions on the above properties were analyzed. It was found that the filling rate of T321 was about 25% when CNTs were filled, and the optimal compounding ratio of the two surfactants, sodium dodecyl benzenesulfonic acid (SDBS) and Tween-80 (TW-80), for the preparation of stable dispersed nanofluids was 3 ∶ 7. The optimum ratio of compound active agent to carbon tube is 5 ∶ 1. When CNTs were acidified for about 9 h and dispersed in sufficient and stable condition, the thermal conductivity of the base liquid was increased by 110% by the composite, and the shape factor of CNTs had the most significant effect on the thermal conductivity. It was found that the composite nanofluids had higher thermal conductivity and lower viscosity than the nanofluids prepared by ordinary CNTs. This was due to the fact that surfaces of CNTs were chemically modified during the opening and internal filling process, so that the composite had better dispersion stability in the base fluid.

“…Metalworking fluids are used extensively in metalworking processes, such as forming, forging and machining [1][2][3]. In machining, cutting fluids (CFs) are essential to reduce tool wear and extend tool life and maintain the surface integrity of the part [4][5][6][7]. The finish machining of turbomachinery components used in aircraft engines is a critical last stage manufacturing process, and CFs are essential to maintain process capability.…”

This paper discusses a method of finish turning Inconel 718 alloy to compare machining performance of a naturally aged and used metalworking fluid (MWF), which had been conventionally managed through its life cycle, with the same new unaged product. The MWF concentrate was a new-to-market bio-ester oil, diluted with water to produce an emulsion. In the experiments, 50 mm diameter bars were turned down with multiple passes at a 250 μm depth of cut to reach a tool flank wear of 200 μm. The machining was interrupted at several stages to measure the flank wear and compare the chip forms for the aged and unaged MWF. The method of finish turning used a small tool nose radius and a small depth of cut that was found to be sensitive in detecting a difference in the flank wear and chip forms for the aged and unaged MWF. On the chemistry, the findings suggest that higher total hardness of the aged MWF was the cause of reduced lubricity and accelerated flank wear. This paper discusses the state of the art with the insights that underpin the finish turning method for the machinability assessment of MWFs. The findings point to stabilization of the MWF chemistry to maintain machining process capability over an extended sump life.
