Effect of Process Parameters on Final Geometry and Quality in Hot Tube Spinning Process

Abstract

Spinning is one of the oldest metal forming processes that produce rotationally axisymmetric and seamless final products by using plates or tubes [1]. Preform can be shaped via rollers, hot or cold and it has a big advantage in terms of manufacturing complex geometries [2]. It is used in many different industries around the world. However, the wall thickness of the output (final geometry) might be uneven or the roller path might be different than expected. It is clear that all of those results have a negative impact on the quality of the process, as they make it difficult to obtain the desired final geometry. Within the context of this study, the cylindrical tube will be used in the hot spinning metal forming process. It will be investigated how the reduction ratio, the roller geometry and the initial temperature of the preform affect wall thickness of the final geometry with the help of finite element analysis software.
