Procedia Manufacturing




Nickel-based superalloys constitute a significant portion of the materials used in important industries such as aerospace, energy production, automotive, and biomedical industries. Due to their superior properties that make them appealing for these industries such as their high strength at elevated operating temperatures, manufacturing these alloys to end product specifications has been a difficult task. Despite the several recent studies that unearth various methods to tackle different aspects of this challenge, machining of nickel-based superalloys continues to be a mostly unknown territory. Researchers have mostly worked on finding optimal machining parameters that provide milder operating conditions, lower cost of tooling, or better end-product dimensional accuracy and surface quality; however, the tool material and type are generally constant in these studies. Therefore, it is difficult to apply the information gathered from these studies when there is a change in the machine tool that has been used, as it frequently happens when tool manufacturers produce new tools that perform better.
