This research aims to promote environmentally friendly manufacturing areas without sacrificing productivity, by the application of biodegradable minimum quantity lubricant (MQL) coolant in end-milling Inconel 718. This study is carried out by comparing a machining cost and method of lubrication applied in the end-milling process. High-speed cutting of Inconel 718 was performed, according to response surface methodology (RSM). Later, the optimization condition of the end mill cutting tool consumption and minimum quantity lubrication (MQL) are evaluated, based on the tool performance; i.e. machining time and material removed. In addition, the number of cutting tool edges is taken into consideration in the machining cost calculation. Machining performance at optimum condition is compared with other research, and the results show that the application of MQL and using ball-nose end mill are competitive, since this type of tool has a high index number which reduces the number of cutting tools required drastically, when compared to other types of cutting tools. The optimization of cutting parameters, with regard to criteria of the maximum material removed (9.03 cm3) and the lowest total cost ($23.55/100 cm3), gives the combination parameter that meets the requirement for green manufacturing; i.e. by reducing the usage of cutting tools and the amount of lubrication consumption.
