The expansion of the metal leads to pressure on the tool when drilling titanium alloys due to their low thermal conductivity. At the same time, the strength of the heat source during shaping largely depends on the friction forces on the working surfaces of the tool, and the effectiveness of applying a nitride wear-resistant coating will largely depend on the ability to reduce frictional interaction on the contact pads. Additional antifriction coatings, which can be applied in various ways, can provide some help here. The paper investigates the effect of PVD DLC coating and epilaming technology on the cutting force and geometric characteristics of the resulting holes.
