The effect of cooling and lubrication on the cutting force during the milling process of Inconel 718

抄録

This paper examines the effects of lubrication and cooling techniques on cutting force generated during milling Inconel 718. The study focuses on three different lubrication cooling strategies, namely dry, chilled, and chilled minimum quantity lubrication (MQL). In this study, the cutting parameters considered are a cutting speed between 100 and 140 m/min, a feed rate between 0.1 and 0.2 mm/tooth, and a constant depth of cut of 0.1 mm. 720 ml/h of Synkool 300G was used as the cutting fluid during the experiments. The results of the experimental analysis reveal that the chilled MQL strategy exhibits a noteworthy reduction in the main cutting force, even under high cutting speed conditions. This reduction in cutting force signifies improved machining efficiency and suggests the effectiveness of chilled MQL as a cooling and lubricating technique during the milling of Inconel 718. This research contributes to the optimization of cutting parameters and the selection of suitable cooling/lubricating strategies for improved machining performance and tool life in Inconel 718 milling.
