Using High Pressure Coolant in the Drilling and Turning of Low Machinability Alloys
The paper examines the results of machining tests carried out on two alloys commonly used in the aircraft industry, specifically, alphabeta type titanium alloy Ti6A14V and nickel-based superalloy of type 718. In view of their excellent mechanical properties and their resistance to a wide range of temperatures, these alloys are widely used in the manufacture of turbo-engine parts. They are extremely difficult to machine, however, for various reasons. The present aim is to consider how their drilling, turning, and milling could be made more productive.
