Abstract: Titanium materials, including titanium alloys, titanium alumina intermetallics, and titanium matrix composites, have broad applications in aero-engine industry for their outstanding properties such as low density, high strength, excellent oxidation, and creep resistance. However, titanium materials are the typical difficult-to-machine materials. Grinding is an important method for high-efficiency and precision machining of titanium materials, which could produce good machining accuracy and surface quality. This paper firstly outlines the application statues of titanium materials in aero-engines and the development of its grinding operation. Then, the research advances on grinding technology of titanium materials are reviewed from the aspects of grinding force and temperature, abrasive tool wear, material removal rates, and surface integrity, followed by a summary of new methods and technologies proposed for solving some critical problems in grinding titanium materials. Finally, the prospect of future research on grinding of these titanium materials is proposed.

Key words: titanium materials, titanium alloys, titanium alumina intermetallics, titanium matrix composites, grinding
