Selection of cutting parameters for the machinability of Inconel 718 using Grey Relational Analysis

open access: yesMATEC Web of Conferences, 2018
Inconel 718 is considered to be most difficult to machine superalloy because of its high shear strength, work hardening and precipitation hardening. Abrasive particles which are in microstructure have tendency have forming chip to be welded to tool and ...
