For prediction and prevention of surface roughening in micro metal formings, a new model to represent material inhomogeneity and an original method to determine the material inhomogeneous parameters were proposed. A series of micro deep drawing were carried out by employing metal foils with thickness of 0.05 mm and average grain size of 16.7 mu m. The validity of the proposed model and method were verified with respect to prediction of surface roughening in the tested micro deep drawings. It has become clear that the proposed model and method for predicting product accuracy in manufacturing medical and electrical micro parts. (C) 2019 Published by Elsevier Ltd on behalf of CIRP.
