The Adaptive Machining of the Leading and Trailing Edges of Precision Forging Blades Based on the On-Machine Measurement

Blades are important components of aviation-engine, with complex shape and high precision machining. The radius of curvature of the leading and trailing edges of the precision forging blades is small and the curvature changes fast. In this paper, the adaptive machining scheme about the leading/trailing edge of the precision forging blade is proposed. Firstly, the measurement model based on theoretical model of the blade is established. Secondly, according to the measurement model, the measurement path planning is proposed. Thirdly, measurement data processing and registration, then blade model reconstructed to generate the new NC code for machining.
