        In this research, the inspection system for the concentricity of hole-saws through the image analysis is developed. The hole-saw, made by being rolled manually with bimetals, is the tool to make a hole in the wall. Its quality is definitely depended on the concentricity of hole-saws. However, it is difficult to check its concentricity and make a decision for the quality control without any automatic inspection system. This research made the automatic image analysis program based on the singular value decomposition model with only a webcam. Experimental results and evaluations demonstrate the validity of the proposed methods.

        The side wall thickness variation of the product to the process of ironing and the die pad was studied using a progressive die of the multi-stage drawing product in the process of ironing and the die pad. Experimental results because ironing is possible to increase the side wall thickness of the product is applied to the intermediate drawing process rather than applied in the initial process. The roundness and concentricity were easy control. A die pad is applied to a stand pad to the sixth step from the first step. The seventh step and the eighth step are applied integrated pad. The integrated pad of the seventh step and the eighth step appeared to be advantageous to control the roundness and concentricity.
