The use of a minimum quantity of lubrication (MQL) with extremely low consumption of lubricant in machining processes has been reported as a technologically and environmentally feasible alternative to conventional flood cooling. In hot machining, the external heat source is applied during machining that will assist to increase machining performance. Many external heating techniques are availabl...

& Minimum Quantity Lubrication (MQL) machining involves the application of a minute amount of an oil-based lubricant to the machining process in an attempt to replace the conventional flood coolant system. Understanding the correlations between fluid properties and MQL performance can help in selecting lubricants from a variety of choices without going through extensive machining tests. This st...

This paper aims to find the key process parameters for machining different parts of an automobile gearbox, commissioned by a company that needs to replace with the MQL lubrication system their current machining process based on cutting fluids. It particularly focuses on the definition of appropriate cutting parameters for machining under the MQL condition through a statistical method of Design ...

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 use of cutting fluid in manufacturing industries has now become more problematic due to environmental pollution and health related problems of employees. Also the minimization of cutting fluid leads to the saving of lubricant cost and cleaning time of machine, tool and work-piece. The concept of minimum Quantity Lubrication (MQL) has come in to practice since a decade ago in order to overco...

In recent years, hard turning has been found to be a well-known substitute for traditional grinding acquiring the finish quality of hardened steel without sacrificing productivity. There are many issues that should carefully understood and dealt with attain efficacious performance in turning. This article discusses modern manufacturing challenges focus on analyzing current state art process ter...

With modern production, Minimum Quantity Lubricant (MQL) technology has emerged as an alternative to conventional liquid cooling. The MQLs is environmentally friendly lubricant method with low cost while meeting the requirements of machining conditions. In this study, experimental and analytical results show that obtained acoustic emission (AE) vibration signal components can effectively monito...

In the current study, internal burnishing process under minimum quantity lubrication (MQL) condition has been optimized to decrease cylindricity (CYL) and circularity (CIC) of burnished hole, while surface roughness (SR) is predefined as a constraint. The optimizing inputs are diameter spray nozzle (D), elevation angle (A), lubricant (Q), pressure value compressed air (P). artificial neural net...

This paper deals with the study of various machining process and show the effect of different cutting parameters on the properties of material. There are several important factors in the product quality which are surface finish, cutting temperature, tool life and coolant quality. The use of coolant generally causes life of tools and it also maintains work piece surface properties without damage...
