Numerical Study of a Process Strategy for Improving Geometrical Accuracy in Incremental Forming Process

Incremental forming process is a relatively new process among researchers, which is yet to be implemented in automotive and aerospace industries. The researchers are studying various process strategies and methods to improve the geometrical accuracy of the parts obtained by incremental forming, because the geometry of the parts is one of the key factors holding back the process industrialization. One good method to investigate the benefits of a process strategy is by means of numerical analysis, from which the results obtained can confirm or disprove the gains of the researched strategy. The aim of this paper is to present the advantages of using a fluid under pressure as a supporting die instead of using a conventional fixed backing plate for the single point incremental forming process.
