Preform design for near net shape close die gear forging using simulation technique 

By Mohammad Haider, K. K. Pathak, Geeta Agnihotri 


In this study, attempts have been made to design preform for near net shape upsetting of gear forging using simulation techniques which is based on the filling of the material during closed die forging. Four types of preforms were tried. Using this parametric study, best die and process parameters are suggested for near net shape gear forging. In present scenario when there are a lot of emphases on accurate design in short span of time. Such study has a lot of industrial value.  

Key-words: Preform; Forging; Simulation; Stress; Metal forming.
