Quantification of the flow lines is very important. Quantification techniques have been developed based on AFDEX's unique metal flow line visualization capabilities, and 2D features have already been introduced. Recently, three-dimensional functions have been added. This function allows the evaluation of the quality of the metal flow lines by a numerical value, which is effective in arriving at an optimal process design and preventing mistakes. Fig.(a) shows the decisive defect of the short-circuited lines while forging a connecting rod, which can be hardly observed from strain distribution in Fig. (b).
