Novel application of ultra-soft and lubricious materials for cutting tool protection and enhancement of machining induced surface integrity of Inconel 718

Inconel 718 is widely used in different industries including aerospace where part quality concerns drive manufacturing process developments. However, despite extensive research, machining of Inconel 718 is still very challenging, often triggering severe surface quality problems. High temperatures and pressures generated at the contact zone during machining of this class of materials as well as high tool wear rates and aggressive built-up edge …
