The cutting fluid has an important role to cool the cutting zone by lubricating the workpiece surface and cutting tools. But if the use of cutting fluid and the disposal method is not carried out properly it can affect human health and have a negative impact on the environment. In addition, expensive cutting fluids make industrial production costs increase. Currently, among the various techniques that exist in metal cutting, one of them is the MQL (Minimum Quantity Lubricant) technique, which is a cutting technique using an air jet to flow it (cutting fluid droplets) into the cutting zone. in the form of a spray. This paper contains an explanation of the MQL technique and various cutting fluid engineering. Several experimental studies suggest that the MQL technique provides better surface finish than dry and wet machining. In addition, the MQL technique also has other advantages such as reducing the coefficient of friction, tool wear, cutting temperature, cutting force compared to dry and wet machining techniques. Therefore, the MQL technique is a viable alternative to lubrication. In addition, the cutting fluid used must also be able to decompose naturally (biodegradable).
