Computer-aided evaluation of cross wedge rolling parameters

Cross Wedge Rolling (CWR) is a metal processing technology in which a cylindrical billet isplastically deformed into an axisymmetric part by the action of wedge shape dies movingtangentially relative to the workpiece. The CWR process offers several innovative featuresover traditional machining operations such as; production capacity, less waste material,strength of product, environmental effect and better product quality.In this thesis, it is aimed to investigate the cross wedge rolling parameters. For this purpose,two set-up has been constructed and extensive experimental investigations have beenperformed on that constructions. In the first type, flat wedge tools are so constructed thatwedges move in opposite directions. In the second type, one of the wedge moves back andforth and the other is stationary. Main phase of this study focuses on the geometry of thewedge. Four zones, namely, knifing, guiding, stretching and sizing zones and two main anglesforming and stretching angles are the main considerations.It is believed that improvements in CWR will make it more viable manufacturing process inTurkey.Keywords: Cross Wedge Rolling, CAD/CAM, Metal Forming
