Abstract
Hot Single Point Incremental Forming (HOT SPIF) is a new technology of forming a metal sheet at high temperatures, especially for hard, high strength materials that are difficult to perform at normal temperatures such as Titanium and other materials. The paper presents the application of simulation method to determine the ability of the deformation of Titanium sheet through the angle of deformation αmax of the lateral profile of the model under the influence of tool diameter D (mm), step in the direction z of the tool VZ (mm), the velocity of the tool Vxy (mm/min), the temperature T(0C). The content of this paper consists of the analyzing the influence of these 4 above parameters by building a finite element analyzing (FEA) model to determine the ability of deformation or the maximum lateral angle of forming and to compare the accuracy of FEM model to the one of Computer-aided design (CAD) model. The paper studies the influences of the 4 parameters to the ability to form of Titanium sheet by HOT SPIF.
