This work proposes an equivalent layered model based on the contour trajectory for Double Sided Incremental Forming (DSIF). The layered deformation and displacement are analyzed for the truncated cones with different height. The displacement for every layer is obtained by numerical analysis and theoretical calculation under the assumption of straight projection. A general method is introduced to estimate the thickness by using of the surface geometry of the desired component. Analytical, numerical and experimental results are compared for the historical displacement, the final geometry and thickness. It is demonstrated that the proposed model and method are reliable and effective in the predictions of historical displacement, geometric accuracy and thickness for DSIF.
