✦ Synopsis

This paper reviews the renewed hobbing process, presents and discusses the technological parameter's of the process, and compares it with cold forging. The renewed hobbing process for the forming of a wide range of mould and die cavities consists of various different hobbing methods, such as penetrative and reduce hobbing, hobbing with a blank holder, hobbing using a pre-heated die blank, etc. Compared to other methods, hobbing allows the achieving of high identicity, excellent cavity surface finish, longer service life of moulds and dies, and cost and time savings.
