dc.description.abstract | new 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 |
