| Abstract: | Experiments have
been carried out to generate data on cold upset forging of unlubricated annealed
commercially pure aluminium, copper and zinc solids of truncated cone billets.
The measured curvatures of the barreled truncated cone billets of all the three
metals are found to closely conform to the calculated values on the assumptions
that the shape of the barrels is in the form of a circular arc. It is further
found that the measured radius of curvature of barrels exhibited a linear
relationship with a geometrical shape factor irrespective of the aspect ratios
of the truncated cone billets. Further, an empirical relationship has been
established between the measured radius of curvature of the barrels and stress
ratio parameter. A comparative study of barreling behaviour of aluminium,
copper and zinc, during upset forging operation in unlubricated condition is
presented in this paper. |
