This not only causes frequent replacement of the dies but also affects dimensional in accuracy and surface finish of the forged parts. Frequent die changes result in not only increase in production costs but also in loss of productive time.</p><p>The objective of this research study was to investigate the forging process of the sponsoring company and suggest improvements which could increase the life of dies used in the process. Literature study showed that there are potential materials and coatings which can be used to increase the die life. Finite Element simulations were used to predict temperatures in the hot forging tooling. As more and more parts are produced, the temperatures in the tooling were found to increase and reach a quasi steady state. Stress analysis of dies could identify locations of high stresses which could assist in improving the forging process in the future.</p><p>The wear prediction methodology was successful in predicting the wear profile in one of the two dies studied. The wear analysis can help design dies with longer life and produce parts with better dimensional accuracy. Finite Element Analysis was also successfully used to find the shrink fit interference which could provide sufficient compression for the extrusion tooling with a ceramic insert.</p> 2010 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1293467038 http://rave.ohiolink.edu/etdc/view?acc_num=osu1293467038 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
