Abstract:
The effect of compressive residual stresses in the surface layers of a workpiece induced by shot peening is used to create a definite shape of workpiece by the process of
peen forming. Informations about all parameter concerning the forming process are a supposition of reproducable manufacturing.
T
he shape of workpiece especially depends on the input value of
workpiece-parameters (like size and material characteristics) and peening-parameters (like number, sequence and shape of indentations). Based on the investigations by
CLAUSEN and MARTIN [5, 6] first new formulas has been developed, characterizing relations between depth and diameter of indentations [h(E), d(E)] and the process-parameters.
U
sing the results mentioned above, a mathematical model to predestinate
the shape of sheet metal workpieces with constant thickness and coverages (< 20%), dependent on peening- and workpiece-parameters, has been built up. It is based on a set
of equations using the statement of quadric surfaces.
