Research on Deformation Control Technology of Large Integral Wall Panel Machining
In order to solve the problem that the deformation of large integral wall board is as high as 40mm after NC machining and can not be shot-peening.The correlation between initial residual stress of blank and the deformation of parts by finite elemtnt simulation method is proposed.The material removal strategy is optimized to effectively control the process deformation of the monolithic wall panels.According to the actual process,the deformation of the parts can be reduced by selecting cutting parameters reasonably,that is using small diameter cutters to pass the tools layer by layer,and adjusting the cutting path from the width direction to the length direction.It is proved that this method can effectively solve the prob-lem of machining deformation of large-scale monolithic panels.
