Optimization of cushion conditions in micro multi-point sheet forming

Journal Article


Abstract


  • Improvement of product quality is required more than ever for mass production of micro formed parts.

    The process of micro multi-point forming with cushion has been simulated in this paper by finite element

    model which incorporates a constitutive relation with consideration of size effect. The effect of the cushion

    material, cushion thickness and coefficient of friction on the surface quality of the deformed sheet

    has been investigated. It has been found that a proper selection of the cushion material and optimum

    cushion thickness can significantly improve the surface quality. In addition, this paper also discusses the

    influence of the cushion material and coefficient of friction on the sheet thickness distribution. Better

    surface quality and thickness distribution can be obtained with good lubricating condition.
