Abstract: Aiming at the major demand for high efficiency and high quality machining of complex blades in national strategic fields such as aviation, aerospace, and energy, this paper reviews the recent advances in the robotic grinding technology using industrial robots as actuators. Specifically, studies in key process technologies from the four aspects of precise calibration of the machining system, efficient matching of the measured point cloud, adaptive planning of the machining trajectory, and precise control of the compliance force are systematically and comprehensively analyzed. Taking the typical steam turbine blades and engine blades as examples, we describe the application effects of the robotic grinding of blades. Finally, the future research directions in this field are prospected from four aspects:integrated machining of special parts of blades, chatter suppression of robotic grinding, surface integrity control, and hybrid additive and subtractive machining of blades.

Key words: robotic grinding, complex blades, machining system calibration, measured point cloud matching, trajectory adaptive planning, compliance force control
