Cutting fluids used in the metal machining industry have exerted serious impacts on environment and human health. In addition, very high cutting heat forces machining-hardened steels been a growing concern field. Hence, new, eco-friendly cooling lubricating techniques are necessary to study develop. Minimum quantity lubrication (MQL) minimum (MQCL) using nano proven as alternative solutions for...

Cutting fluids can be used to cool workpieces at high cutting speeds and remove chips from zones. The effectiveness of may improved with the addition hybrid nanoparticle dispersion. This study evaluates an Al2O3-TiO2 as a fluid in turning operations. nano-cutting was prepared using one-step method computer numerical control (CNC) coolant concentrations up 4%. Utilizing air-assisted injected thr...

The use of effective software in Computer Aided Process Planning (CAPP) can contribute significantly towards cost reduction and improvement in production rate. The most important elements of CAPP are the ability to effectively evaluate various machining process sequences and the utilization of the most appropriate machining parameters including machines, tools and tool grades and tool angles, c...

Annealed metals are surprisingly difficult to cut, involving high forces and an unusually thick "chip." This anomaly has long been explained, based on ex situ observations, using a model of smooth plastic flow with uniform shear to describe material removal by chip formation. Here we show that this phenomenon is actually the result of a fundamentally different collective deformation mode--sinuo...

The reproducibility of a reaming test was analysed to document its applicability as a performance test for cutting fluids. Reaming tests were carried out on a drilling machine using HSS reamers. Workpiece material was an austenitic stainless steel, machined using 4.75 m·min cutting speed and 0.3 mm·rev feed. A mineral straight oil and a water-based lubricant at two different oil concentrations ...

Today one of the top priorities in the machining industry is to increase or retain the profit margin through cost reduction. In addition, consumers are becoming increasingly aware of the impact that the life cycle of products has on the environment, at the time of their choice. So companies are required to research and develop sustainable processes or adapt existing ones. This research has been...

The machinability of titanium alloys still represents a demanding challenge and the development new clean technologies to lubricate cool is greatly needed. As sustainable alternative mineral oil, esters have shown excellent performance during machining. Herein, aim this work investigate influence esters’ molecular structure in oil-in-water emulsions their interaction with surface form lubricati...
