Title: Experimental and numerical research on incremental sheet forming
Abstract: In order to find a method to reduce excessive sheet thinning of parts by incremental sheet forming,taking typical conical part as an example,an elastic-plastic finite element model was developed using ABAQUS,then the influences of some relevant process parameters were discussed,such as half-apex angle(α),tool diameter(D) and step increment(ΔZ).The results show that half-apex angle is the dominating process parameter to impact the formability of material,as the half-apex angle increases,the smallest thickness of part increases and the deformation of sheet is more uniform.Small step size and big tool diameter have a good influence on strain distribution and surface quality;as the tool diameter,step size and half-apex angle decrease,the axial forming force is smaller.The simulation results are in good agreement with experimental results.
