Research on Precision Forging Blade TENON Processing Technology

摘要

TENON machining is an important and major processing for aero-engine precision forging blade. Traditional processing methods for TENON machining cannot meet the modern aero-engine performance, efficiency and environmental protection needs. In the paper, a "hard" clamping process method to machine blade TENON is proposed, and the key technologies of the method, fixture layout optimization and deformation controlling, are discussed in detail. Finally, we introduce specific scheme that designed a set of hydraulic special fixture with adaptive auxiliary support to realize "hard" clamping processing.
