Development of Advanced Carbide for Nickel-Based Alloy Machining for Turbine Engines

Abstract

Modern gas turbine engines (Figure 1) used in military fighter jets depend on nickel-based super alloys for their critical components due to their ability to withstand high combustion temperatures. However, the very characteristics providing good high temperature strength in these alloys make them difficult to machine efficiently by limiting the speed capability of the cutting tools. A joint effort between the NCDMM and alliance partner Kennametal, Inc. involved developing an advanced coated carbide cutting tool for turning nickel-based alloys such as Inconel 718 with 40% higher machining productivity.
