Orbital (rotary) forging is one of

Orbital (rotary) forging is one of metal forming processes for
producing mechanical parts. Scientific researches on orbital forging
based on numerical analyses have been carried out for over 30
years. A thorough analysis of the relevant literature demonstrates
that this problem is relatively difficult and both theoretical and
technological knowledge about the orbital forging process is still
far from being complete. This is especially evident as far as forming
parts with complex shapes is concerned.
