Abstract: The present paper confers about design and analysis of double collar collet chuck holder (DCCCH) by combined extrusion and forging (CEF) process. The current work addresses the problem to estimate the parameters such as metal flow, heat transfer, friction, punch load and ram speed during the CEF process. It should be noted that complexity of shape and volume of the material are two major constitutes which ensign motivation for the present work. In this context, framework of the present in-situ focus on estimation of aforementioned parameters which enables us to develop complex shapes with minimal material wastage using CEF process. Henceforth followed by analytical and numerical solutions have been developed adjacent to the experimental procedure.
