“…Although, cutting fluids are beneficial in the industries, today their uses has been questioned around the world, due to environmental consciousness enhanced laws and regulations [34]. The use of cutting fluids has several adverse effects such as environmental pollution, dermatitis to operators, water pollution and soil contamination during disposal [35][36][37].…”

Hard turning processes have several advantages against traditional turning. Improved surface integrity and short process time are some examples. Surface integrity is one of the most important issues in modeling of machining processes. Multiple roughness parameters are observed in relation to several controllable and uncontrollable input parameters. Since these multiple roughness parameters are correlated, multivariate methods are the most suitable approach for process control. This research aims to propose a method for assessing stability and performance of multivariate processes in the presence of noise variables. A hybrid method based on design of experiment, statistical process control and principal component analysis was applied to AISI 52100 hardened steel turning. The process performance index was obtained within the range of 0.18 to 1.11. The best process performance was achieved taking cutting speed of 170m/min and lubricating fluid flow of 3 L/min.

“…Siller et al [8] performed experiments to determine the heat dissipated during the turning operations by using internal cooled cutting tools. They measured the temperature at the inlet and outlet of the cooling channels and found that the temperature of the tool tip were lower than the temperature obtained during dry machining.…”

Nimonic C-263 is a British nickel–chromium–cobalt–molybdenum alloy specially meant to be used in high-temperature and high-strength applications. Consequently, it produces high thermo-mechanical loads on the machining tool when machined. As a result, excessive heat is generated during dry drilling, between Nimonic C-263 and tungsten carbide tool coated with Alcorna, which in turn reduces the durability of the tool. In order to determine the temperature distribution of the tool, the coupling of finite element machining simulations along with computational fluid dynamics simulations is performed. The temperature distribution of the tool under dry condition is simulated via the DEFORM 3D software and the Altair AcuSolve software. Further investigation under cooling condition is performed using Altair AcuSolve software. The mass flow rate of the coolants is kept constant when the temperature distribution is obtained during the CFD analysis under cooling condition. Silver nano coolant has high heat reduction compared to other coolants and is found to generate 34% less heat than dry condition.

“…Applying the cutting oils can reduce friction generated between cutting tool and workpiece as well as high temperature production during a process by dissipating the initiated heat. To highlight, letting the cutting oils to flow over the tool and workpiece [2] can avoid destruction of workpiece material and cutting tool due to the thermal damage during the cutting process. Therefore, providing a great cooling and lubricating effects can improve manufacturing operations and thus increase productivity.…”

“…High pressure cooling machining is among the most effective ones as it utilizes coolant jets with accurate alignment and extremely high pressure. Despite widely used in machining tough materials in aerospace industry [2], cryogenic cooling machining is characterized as an ecological machining technology since it applies liquid nitrogen or frozen carbon dioxide as the coolant. Furthermore, minimum quantity cooling lubrication (MQCL) machining is said to be more effective and productive as it can be used in universal condition.…”

“…MQL used compressed air and oils as its lubricant whereas MQC employs emulsions rather than oils. However, MQC does not widely used in industry as its emulsion produce low lubricating effect compared to MQL [2] that brings in numerous advantages to the manufacturing sectors. With very little supply of lubricant, it is still capable in lengthening the cutting tool life and refining the machining performance in the aspects of the workpiece surface roughness, cutting force needed as well as its process capability.…”

Application of cutting oil during machining process has been the most important contributor for the development of manufacturing sectors. There are many types of machining technologies developed with cutting oil supply system such as minimum quantity lubricant (MQL). With very little supply of lubricant, it can lengthen the cutting tool life and surface roughness of workpiece. Although the low consumption of lubricant is favourable, study on the performance of MQL machining process must be strengthened enough since the high penetration ability of very little amount of lubricant oil is important. Many researches have been carried out since decades ago to study the MQL performance. However, investigation on the effects on nozzle position have not been treated in much detail. Here, this paper is aimed to investigate the effects of nozzle distance to surface roughness of workpiece under MQL milling process. Experimental approach was done mainly under different nozzle distance varied in horizontal direction from the cutting tool. Other than that, the effects of feed rate and spindle speed to the surface roughness were also investigated. As a result, surface roughness increases with increasing feed rate. At lower operation of spindle speed, surface roughness rapidly increases with increasing feed rate compared to higher operated spindle speed. Operation under high feed rate leads to a decreasing surface roughness with increasing spindle speed. Milling under high feed rate for all conditions of nozzle distance can still give a great surface roughness for a workpiece, only if the spindle speed is increased. Surface roughness decreases with increasing distance of nozzle to workpiece in horizontal direction.
