Abstract:
|
This paper studys the mechanism of fine blanking process by matrix algebra of large de- formation and grid experiments.The experiment parameters include the clamping force and die clear- ance.The investigation results reveal the rules of the change of major principal strain,the direction and rigid body rotation with the process parameters.This study indicates that the rigid body rotation impli- cates a significance in fine blanking deformation.
