Machining Nickel Alloys: Avoiding Common Mishaps
As nickel alloys are being machined and heat is generated, chips tend to become stringy and weld themselves to a tool's cutting edge. This phenomenon, built up edge or BUE, rounds the cutting edge of the tool, resulting in poor cuts and increased friction, thus further contributing to work hardening. An example of BUE is seen in the …
