In order to obtain high-precision three-dimensional pieces by dry pressing, two approaches were studied: modelling the
material flow and strain during pressing; and evaluating the bulk density (Da) distribution in a pressed piece and using
shrinkage models that allow the post-firing geometry to be predicted. It would thus become possible to act in the design
phase (functional geometry and rear) and in the process.
This paper describes the studies carried out to predict the final geometry of three-dimensional pieces of the sheet type
obtained by conventional pressing techniques, from the Da distribution in each point of the piece. For this purpose, pieces
were modelled using finite element method (FEM), applying simulation processes to obtain the strain at each point of the
piece as a function of its Da. The experimental validation was performed using the X-ray absorption method for Da and a
CMM (coordinate measuring machine) for the geometry [-]
