It is influenced greatly by the slendernessratio of the cylindrical billet and the slope of the wedge on the tool of skew rolling. Using the numerical simulation, the lawof variation in NCVR during the forming process is found out. At the same time experiments have been carried out underdifferent conditions, the result of which are found to be in good agreement with the theoretical predictions. 关 键 词：SKEW rolling, FEM, Non-column VOLUME
