| Abstract: | In this paper, we present an optimal method for homogenizing wall thickness of the large tube shaped part, which has the interior non working surface and the exterior high precision working surface. Based on the machined exterior surface, the wall thickness of the tube shaped part has been measured. Thus we can obtain the geometric central line of the non working interior surface indirectly. The least square method for determining the geometric central line was given. According to the optimization results, we can not only guarantee homogenizing the wall thickness of the tube shaped part, but we can also accurately determine whether the blank is qualified or not. Computation examples show that this method is very simple, reliable and effective. |
