“…Moreover, it is believe that there is excessive coolant from 30s coolant on to provide good lubrication at the cutting area although the coolant is off for 30s. This is in conjunction with the results of Jessy et al [14], where they indicated that the development of chips during machining tends to arise through coolant. When the coolant is delivered to the machining area and the amount of coolant is too large, the chips cannot emerge from the cutting zone.…”

Surface completion is a significant proportion of item quality since it extraordinarily impacts the presentation of mechanical parts. In CNC machining, wet cooling technique is normally applied to provide lubrication at the cutting zone to obtain good surface finish. In this system, a lot of cutting liquid is provided ceaselessly at the slicing zone to decrease the temperature between cutting instrument and work piece. Despite the fact that the cutting liquids are useful in ventures, their harmfulness can give negative effect to condition, human wellbeing and increment creation cost. Moreover, it is discovered that, solitary a limited quantity of coolant assumes their job in the cooling framework application. Therefore, an Arduino time base computerized coolant supply is created as another framework to diminish the utilization of cutting liquids. In this examination, an Aluminum Alloy was machined with CNC processing and the surface harshness is seen by utilizing this framework. As per the trial results, it is seen that the best time interim for providing and quit providing the coolant is 30 seconds with the surface harshness estimation of 1.0470 µm utilizing the shaft speed of 1200 RPM, feed pace of 100mm/min and profundity of cut of 0.4mm.This technique can reduce the cutting fluid consumption during machining operation and the improvement of the surface roughness is also obtained.

“…Therefore, it is substantial to understand how drilling temperatures are affected by the drilling parameters. 5 , 52 The amount of generated heat and consequent temperature level of both drill bit and workpiece are desired to know for drilling of composites. The generated heat by the friction between the tool and workpiece dissipates by the workpiece, the tool, chips, and the environment.…”

The present work deals with temperature effects and parametric optimization in the drilling of continuous glass fiber reinforced epoxy composite. Drilling ability was examined operating a drilling system with different drill bits, feed rate, and spindle speed parameters. The investigation was performed by changing the tool and composite interface. Drilling experiments were carried out under the dry condition. Thrust force and drilling temperatures were measured using dynamometer and thermal camera. Peel-up and push-out delamination were evaluated using an image analyzing tool. Results show that the tribo-mechanical behavior of the drilling operation is affected at different levels by tool coating. This behavior is related to the intrinsic friction properties of coating nature. Response surface methodology was used in the evaluation of experiment results. The feed rate of 0.13 mm/rev, spindle speed of 2425 rpm and HSS-TiN drill bit are found as an optimum drilling parameters and drill type.

“…However, due to the lack of coolant or lubrication on the surface of machining tool and workpiece, more friction, heat, and adhesion were generated which results in high level of abrasion, diffusion, and lower surface finish and tool life [ 74 , 75 ]. Thus, many researchers have been conducting studies on using alternative methods of conventional cutting fluids applications such as flooded and minimum quantity lubrication techniques [ 76 , 77 , 78 , 79 , 80 ]. Conventional application of cutting fluids such as flooded machining and dry machining have been questioned for their sustainability in the machining industries which caused numerous environmental issues and health and safety concerns [ 81 – 86 ].…”

This paper reviews recent progress and applications of usage of cutting fluids in conventional machining processes. In addition to reviewing the various conventional and advanced cooling techniques during machining, the paper also discusses the use of minimum quantity lubrication (MQL) in several types on metals such as steel, aluminum, alloy, and titanium alloys. Due to the toxicity of conventional cutting fluid resulting in ecological problems, the demand for environmentally friendly cutting fluid is rising. Therefore, natural vegetable oil is chosen as potential replacement as an environmentally friendly cutting fluid which fulfills the important aspects of biodegradability and sustainability. Application of vegetable oil-based cutting fluids under MQL techniques are also discussed. Moreover, the potential of palm oil as biodegradable and environmentally friendly natural vegetable oil-based metal-working fluids in MQL are reviewed.
