S1303-1-5 Cutting Characteristics of 64Fe-36Ni Heat resistant alloy with End Milling

Abstract

The nickel base high temperature alloys are generally considered difficult-to-cut due to its low heat conductivity and high tenacity. This paper deals with machinability grooving cutting of 64Fe-36Ni alloy. Specimens were end-milled to determine how cutting speed would affect tool wear and cutting force. The tool face tends to wear more significantly as the cutting speed increases. The faster cutting speed gives the cut surface smoother finish by burnishing effect.
