The effect of pressing direction on the 5-axis CNC incremental forming quality

摘要

The effect of pressing direction on forming quality in the 5-axis CNC incremental forming was studied by using the digital simulation technology based on the finite element analysis method. Four kinds of finite element analysis models were created according to the different pressing directions, and were simulated by using ANSYS/LS-DYNA software. Through comparing with the simulation results of the four kinds of finite element analysis models, the relationships between the pressing direction and sheet thickness distribution, sheet thickness thinning rate, outline of the middle surface and the equivalent strain of middle surface were presented.
