Outline of Final Research Achievements

The present study proposes a new near-net-shape multi-stage shaft working method to partially and simultaneously control multi-cross-section through metal molds, based on the diameter- enlargement working method developed by coauthors. The study designs a finishing machine and decides optimum processing conditions for improving the machining accuracy of processed part. Furthermore, the study surely achieves the omission of after processing like cutting and improvement of yield rate and it is expanding into an excellent near-net-shape processing technique in viability.
