dc.description.abstractnew flexible experimental technique is introduced where a tool base that incorporates sensitive pressure pins is used. An industrial - tool that contains the forging geometry can be placed on top of the base tool that includes the measuring devi ces. The two tools are inter - linked together and pressure pins are inserted through them but concealed from the contact sever conditions. This paper examines the application of measurements of stresses during the deformation of cylinders and rings. Stres ses normal to the tool are measured by using pins that are perpendicular to the surface of contact. Friction stresses are obtained by using inclined pins. Friction characteristics in metal forming operations are usually evaluated by the use of the ring c ompression test and an average estimate of the friction resistance for the whole pattern of deformation is estimated from the deformation of the inner and outer profiles of the ring. The neutral radius, which exists inside the deformation pattern, is ide ntified in both experiments and theory. Also, experimental measurements of stress components compared favourably with those values obtained theoretically.en
