External thread turning is a complex 3-D process in which the cutting conditions vary over the thread cutter profile. There are a lot of factors that affect the thread precision. This paper focuses on the influences of the lubrication method, cutting speed and the number of passes on the thread precision. Several stainless steel turning tests were conducted. The results showed that lubrication method was the most important factor that affected the thread precision, while the number of passes was the least important one. MQL (Minimum Quantity Lubrication) could reach the effect corresponding to wet cutting at specific cutting parameters and showed great potential to replace traditional lubrication method.

Ultra-precision machines are widely used to turn aspherical profiles on mould inserts for the injection moulding of optical lenses. During turning of a profile on a stainless steel mould insert, the cutting speed reduces significantly to 0 as the cutting tool is fed towards the center of the machined profile. This paper reports on experiments carried out to study the wear of uncoated, PVD-coated and CVD-coated carbide tools in the ultra-precision machining of STAVAX (modified AISI 420 stainless steel) at low speeds.

The turning Process is the main processes used in automotive parts from more productivity, it requires the cutting velocity and feed rate high. And from those cutting, it causes high temperatures on cutting and a tool life of cutting tools decreased. Therefore using of cutting fluid (Coolant) is one of the commonly used methods to reduce temperatures that occur while cutting, reducing the wear of cutting tool and helps extend the tool life of the cutting tool. However, cutting fluid it's not always a good way, from the high cost and environmental problems issues. Using the MQL technique is one of the alternatives that using more nowadays to solve the above mentioned problems. This research proposed a MQL technique substitution of cutting fluid that using in the current process by applying in order to obtain the proper cutting condition for carbon steel material grade SAPH370 with the carbide cutting tool. The cutting conditions will acceptable from the minimum quantity of lubricant and the maximum of tool life of cutting tool under surface roughness (Ra) is less than 1.2 μm. The proper cutting condition determined at a feed rate of 0.10 mm/rev, a cutting speed of 300 m/min and a flow rate of 5ml/hr.

Nowadays, an increase on demands of aerospace components has led to implementation of high speed machining (HSM). The principal factors in the performance of aerospace materials are strength-to-weight ratio, fatigue life, fracture toughness, survivability and of course, reliability. However, when HSM is coupled with dry or near dry machining, it will present considerable technical challenges to the manufacturing sector especially when the integrity of the machined surface is concerned. In this investigation, the effect of high speed drilling (HSD) conditions on the performance and surface integrity of Inconel 718 were studied. Hole was drilled individually using TiAlN coated carbide insert drill (14 mm in diameter) under minimum quantity of lubrication (MQL) condition. Results showed that uniform flank wear and chipping were the dominant tool failure modes. Moreover, the results showed an increase in cutting temperature with increasing cutting speed and feed rate. Thrust force and torque decreased linearly with the increasing cutting speed but significantly increased when higher feed rate is employed. Cutting speed significantly influenced the distribution of surface roughness value. Variations of hardness readings were recorded beneath the machined surfaces, they were due to the hardening effects caused by concentration of high temperature and stresses on the workpiece.

The present research addresses the machinability of hardened die steel (AISI D3, 61HRC) in hard turning using multilayer (TiCN/Al2O3/TiN) coated carbide tool under nanofluid based minimum quantity lubrication-cooling condition, where no previous data are available. Power consumption, flank wear, chip morphology and surface integrity (microhardness, residual stress, white layer formation, machined surface morphology, and surface roughness) are considered as technological performance characteristics to evaluate the machinability. Combined approach of central composite design - analysis of variance, response surface methodology and desirability function analysis have been employed respectively for experimental investigation, predictive modelling and multi-response optimization. With a motivational philosophy of “Go Green-Think Green-Act Green”, the work also deals with energy saving carbon footprint analysis and sustainability assessment to recognize the green manufacturing in the context of safer and cleaner production. under environmental-friendly nanofluid assisted minimum quantity lubrication condition. The quantitative analysis revealed that the cutting speed influenced the power consumption during hard machining (75.78%) and flank wear of coated carbide tool (45.67%); feed rate impacted the surface finish of the machined part (68.8%) significantly. Saw tooth shapes of chip produced due to cyclic cracking. Due to low percentage contribution of error (5.32% to Ra, 6.64% to VB, and 7.79% to Pc), a higher correlation coefficient (R2) was obtained with the quadratic regression model, which showed values of 0.9, 0.88 and 0.92 for surface roughness, flank wear, and power consumption, respectively. Optimization with the highest desirability (0.9173) resulted the optimum machining conditions under NFMQL at the cutting speed of 57 m/min, depth of cut 0.1 mm, feed of 0.07 mm/rev, and insert’s nose radius of 0.4 mm. As a result, under NFMQL tool life was improved by 30.8% and 22.6% in respect of flank wear and surface roughness respectively than when machining with MQL technique by adapting the optimum machining condition. Therefore, using hard nanoparticles-reinforced cutting fluid under minimum quantity lubrication condition in practical manufacturing becomes very promising to improve sustainability.

Cooling And Lubrication

Difficult-to-cut materials have been widely employed in many engineering applications, including automotive and aeronautical designs because of their effective properties. However, other characteristics; for example, high hardness and low thermal conductivity has negatively affected the induced surface quality and tool life, and consequently the overall machinability of such materials. Inconel 718, is widely used in many industries including aerospace; however, the high temperature generated during machining is negatively affecting its machinability. Flood cooling is a commonly used remedy to improve machinability problems; however, government regulation has called for further alternatives to reduce the environmental and health impacts of flood cooling. This work aimed to investigate the influence of dispersed multi-wall carbon nanotubes (MWCNTs) and aluminum oxide (Al2O3) gamma nanoparticles, on enhancing the minimum quantity lubrication (MQL) technique cooling and lubrication capabilities during turning of Inconel 718. Machining tests were conducted, the generated surfaces were examined, and the energy consumption data were recorded. The study was conducted under different design variables including cutting speed, percentage of added nano-additives (wt.%), and feed velocity. The study revealed that the nano-fluids usage, generally improved the machining performance when cutting Inconel 718. In addition, it was shown that the nanotubes additives provided better improvements than Al2O3 nanoparticles.
