- The tilting index table has attached to CNC machining center with 3axes, it can be improvement of its performance and its machining efficiency. The tilting index table is a key unit in order to manufacture some non-rotational and 3-dimensional parts, using the conventional machining center. The tilting index table is directly connected to a processing object. Regarding the increase in the deflection of the table, it directly affects processing objects and increases errors and that makes impossible to obtain desired processing precision. Thus, this study performed the shape optimization of air pockets in order to minimize the deflection presented in the existing table. In the numerical optimizing method for implementing optimal design, the general full factorial design and response surface method in the design of experiments were used. A finite element analysis was used for computational experiments in which the finite element analysis was performed by using the ANSYS Workbench, which is a type of commercial FEM tool. In addition, the analysis of the results was performed by using the commercial program, Minitab 15. The results show that the optimum design results is better than those of the initial design.
