The main characteristics of gamma–TiAl intermetallic compounds were introduced. Poor plasticity and tenacity

low thermal conductivity are the main factors that lead to high cutting temperature

high cutting force and poor surface quality. The typical machining and non-traditional machining methods of gamma–TiAl intermetallic compounds were summarized from the aspects of tool life

machining efficiency and surface quality. And we consider that grinding and electrochemical machining are suitable machining methods at present. However

there is still a lack of processing technology that can give consideration to efficiency

cost and surface quality.
