• In the processes of components-rolling, we cannot always get a product with sufficient form and quality due to their particular deformation mechanisms. In order to reveal the detailed mechanism of deformation, a series of experimental studies has been carried out. In this paper, cases of plain cylinders being rolled between plain flat dies are dealt with. Configuration and deformation of the material in rolling are clarified. By means of examining the normal and tangential components of force acting on the die face with two kinds of specially equipped dies, the distribution of the components of stress has been newly estimated. Experimental results are supported by proposing a new type of shear line field according to which a far advanced information on the essentials of deformation can be made available.
