The six machining parameters, namely cutting tools for different materials; depth of cut; cutting speed; feed MAR-M247 is an equiaxed (EQ) or polycrystalline nickel-base superalloy that was developed at the Martin Marietta Company in the 1970s [8]. The mAR- m247 superalloy is being increasingly used in gas turbine blades [6]. Sep 1, 2011 · The purpose of this study aims at the machinability of Nickel-base alloys. This study used three Ni-based superalloys such as Mar-M247, Haynes-230 and Inconel-718，applying thermal friction drilling to conduct experiments on the CNC machine using spindle speed and feed rate as process parameters employing Taguchi methods to explore the bush length and internal hole of drilled surface roughness。 Mar 1, 2021 · The MAR-M247 superalloy was initially developed for vacuum investment casting of turbine components by the Martin Marietta Corporation in the early 1970s [10]. , 2021: Multicut technology used in WEDM machining of Mar-M247. Further possibilities of microstructural optimization and the design philosophy are discussed in the light of the Binder Jetting process-chain. Over the last few decades, this alloy has been extensively used in the production of advanced turbine blades and rotating parts in the aerospace industries because of its excellent thermo-mechanical properties. Chemical Composition The following table outlines the chemical composition of Mar M 247™. Abstract This study investigates the properties of machin-ing MAR-M247 nickel-based superalloy combined ultra-sonic vibration with high-temperature aided cutting. Due to their mechanical properties, their machinability by conventional technologies is relatively difficult, so wire electrical discharge machining (WEDM) is widely used, where only one Wire electrical discharge machining (WEDM) technology is often used for the final machining of parts to the required surface quality without further finishing o Milan Kalivoda's 9 research works with 59 citations and 227 reads, including: Multicut technology used in WEDM machining of Mar-M247 MAR-M247 Spherical Nickel-Based Alloy Powder is a high-performance material designed for the most demanding environments.
