Experimental Study of MQL Performance on the Titanium Material Drilling Process

This titanium material is very difficult to machine due to its low thermal conductivity resulting in heat generated when machining accumulates in the cutting zone. This causes the thermal effect to be absorbed in the drill tool so that the tool wears out quickly which affects the quality of the hole. This study aims to examine the effect of tool wear on the cutting force of hole quality under dry machining conditions and machining using the MQL method. The cutting force resulting from the process of drilling holes using MQL is smaller than drilling in dry conditions. The larger the feed (f), the greater the cutting force (N) that is generated during the drilling process in dry conditions and MQL conditions. The greater the cutting speed (v) used during the drilling process, the lower the cutting force generated
