Influence of Process Parameters on Amount of Deformation During Warm Reshaping of Blade

In the forming process of blade,the warm reshaping is a key working procedure to ensure blade dimensional accuracy. The orthogonal experiment of deformation amount of blade was done according to temperatures,pressure and dwell time,the experimental data was analyzed by variance analysis,the optimal reshaping process parameters were defined. The production shows that the warm reshaping process is fitting,which can provide reference for controlling deformation amount of thin sheet during reshaping.
