摘　　要：压气机钛合金叶片为航空发动机关键零部件,其制造质量和加工精度对整机工作性能有至关重要的影响。由于该叶片型面结构复杂,打磨工作常由人工完成,其打磨效率低,打磨质量一致性难以保证。对航空发动机钛合金叶片机器人浮动砂带磨削技术进行分析,并进行了相关试验研究。试验结果表明钛合金叶片的机器人浮动砂带磨削技术能适应钛合金叶片的打磨要求,打磨后的叶片表面粗糙度Ra在0.4μm以内,表面三维形貌一致性较好,磨削后的进排气边的形状保持一定的圆度状态。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.
