The efficiency of the tools designed on the basis of either CRHS or CMSR concepts can best be assessed by considering the reduction in the levels of redundancy achieved in a number of individual processes. The present chapter is concerned entirely with an examination of metal flow through geometrically different, but theoretically related, zones of deformation, and also with a comparison between the redundant effects in passes so designed and those often used in industrially operated processes.
