Abstract
Incremental forming is a potential process for sheet metal prototyping. In this one more spherical headed tools are moved along specified path to deform the sheet in to required process. In single pass incremental forming, it is not possible to form the sheet with vertical walls. Thus the maximum wall angle that can be formed is used as a parameter to asses the formability. In the present paper the maximum achievable wall angle in incremental forming of EDD steel is predicted using two different geometries. First one is, continuously varying wall angle conical frustum and the second one is, continuously varying pyramidal frustum. The experimental values are compared with the values obtained by the numerical simulations using LS-DYNA software. A good correlation was observed between experimental and simulation results.
