In order to raise profits of the wheel, the manufacturing cost must be lowered. The forged part is deformed during forging processes, so the processing tolerance must be taken into consideration in the process design. Hence the used material is increased and further machining is necessary. The measurements of geometric contour can provide useful guidelines in inspecting quality and designing processes of the wheel. In this study, the reverse engineering is used to acquiring geometric features of aluminum wheel. The measuring data of wheel contour through two cooling processes, air cooling and water cooling , are obtained by the laser scanning system. Then the wheel surface is reconstructed by the reverse engineering software Geomagic Studio. The deformed shapes between two cooling processes are compared to show the effect of cooling process on geometric features of the forged wheel. The results show that the reverse engineering technique is a feasible method in acquiring geometric features of forged parts.
