In the manufacturing industry, both the metalworking and the measuring are important. Especially, high-accuracy measurement is necessary to make quality products. The effective metalworking and the measurement technology should be also necessary for the shipbuilding industry as a matter of course. The purpose of this paper is to investigate the possibility of introduction of the three-dimensional noncontact measurement technology to the metalworking processing, based on the detailed investigation of working situation on the shipbuilding process. As a result of the ratio-delay analysis on the roll-forming work, it is clear that the work for the measurement of shape is responsible for a large share of the turnaround time of the working. However, it should be noted that the time of measurement work is not the nonperforming time. Because the three-dimensional laser scanner is a remote surface profile system, it is expected of much help to the 3-D measurement work of the metal components. However, the utilization of the 3-D laser scanner is never directly useful for the effective roll-forming work in the shipbuilding process. It is necessary to evaluate the effectiveness of the introduction of the new technology based on the industry engineering. And, we hope that more useful technology will be put into practice very soon.
