Introduction Titanium alloys are known as difficult-to-machine materials, especially at dry machining, due to their several inherent properties[1-3].
At lastly, metals which are more adhesive tend to exhibit more ductility at elevated temperatures, thereby leading to possible cold-welding between the abrasive grits and workpiece materials.
