Abstract Compressor titanium alloy blade is a key part of aero-engine, and its manufacturing quality and processing accuracy have a crucial impact on the overall performance. Due to the complicated structure of the blade profile, the grinding work is often done manually, the grinding efficiency is low, and the consistency of the grinding quality is difficult to guarantee. Therefore, this paper analyzes the floating belt grinding technology for robotic belt grinding of aeroengine titanium alloy blades, and conducts relevant experimental research. The experimental results show that the robotic floating belt grinding technology of titanium alloy blades can meet the grinding requirements of titanium alloy blades. The surface roughness Ra of the blades after grinding is within 0.4µm, and the three-dimensional topography of the surface is consistent. The shape of the exhaust side maintains a certain roundness.
