Improve Machining of γ-TiAl#

© WZL der RWTH AACHEN

How can the machining processes of Titanium aluminides be improved?

 

Challenge and Motivation

  • Poor machinability due to mechanical properties
  • Excessive tool wear and low surface quality

Objectives

  • Milling
    • Identification of cooling lubrication strategies for improving tool life and surface quality
    • Development of cutting tool material and/or coating system for increasing tool life
  • EDM/ECM
    • Identification of suitable machining parameters for EDM/ECM processes including achievable tolerances
