An investigation of cutting forces and tool wear in turning of Haynes 282

Abstract

Superalloys belong to the group known as difficult to cut materials, and inside this category of material Haynes 282 is considered a novel material with huge applicability subjected to automobile, aerospace and gas turbine industries. The characterization of machining of this new material evidences a lot of importance. Therefore, this paper presents an experimental investigation into the effect of lubricant pressure and material heat treatment on cutting forces, machined surface quality and tool wear evolution on turning of superalloy Haynes 282. Face turning of hollow discs with fixed cutting conditions with cemented carbides tools where carried out to evaluate machinability. The results show that Haynes 282 Alloy in solution annealing Large Grain Solution (LGS) state has better machinability than precipitation hardened Large Grain Aged (LGA) state in terms of force levels and tool wear. In terms of coolant pressure effect, a significant improvement is not observed in the case of High pressure coolant (HiPC).
