Research on the Hole-Flanging Based on Three-Stage CNC Incremental Forming
Aiming at the problem of the hole flanging forming on thin-walled parts,the method and process flow of the hole flanging forming based on three-stage CNC incremental forming technology were studied.The methods for supports design,forming model modeling and forming path generation of each intermediate stage of the three-stage CNC incremental hole flanging forming were studied.The finite element numerical simulation of the hole flanging process based on the three-stage CNC incremental forming technology were carried out using ANSYS software.Based on the analysis of the thickness,thinning rate and contour dimension accuracy of the flanging hole,the method for improving the contour dimension accuracy of the flanging hole was given.
