| Abstract: | Accuracy of the
forging parts becomes critical as the process depends on many factors. Defect
may harm the assembly and tends to affect the performance of the parts.
Therefore, it must be understood and detected as soon as the manufacturing
begins. The size and complexity of the part limit the defect to be assessed.
This study intent to investigate the defect of
the cold embossing pin located at the head of a propeller blade. This is to
ensure accurate assembly of the blade. In this work, the effects of design and
process parameters on the formation of defect are studied using 2-D finite
element analysis. The defect can be measured based on the incomplete filling of
the region using the captured images from the FE result.
The results seem to show that there is less effect from the diameter of punch
and internal cavity, but more obvious due to the distance to the edge. The FE
results are in good agreement with the experimental results. |
