    In the checking phase of automobile repair painting, the position from which the experts see the painted surface was clarified using three-dimensional motion analysis. The expert stood approximately 1200 mm away from the damaged area and looked at the damaged area without lowering the head.

    Auto repair sheet metal work refers to the work of repairing a damaged part without replacing any of them. Repair technicians are required to have a high level of skill and to be able to work flexibly. If the work of experts can be quantified and visualized, it may be possible to transfer the skills to non-experts in a shorter time. Thus, in this study, technicians repaired a dent made on the press line of a passenger car fender using a hammer and dolly. The purpose of the research is to analyze the working time and working process during the repair. The sheet metal repairs were classified into five steps: “Hammering” (H), “Adjustment and position check of the dolly” (D), “Check by hand” (CH), “Check by eye” (CE), and “Other” (O). It was found that experts tend to spend longer than non-experts on step D.

    In this research, motion analysis was carried out to formalize the practical backing technique of experts and to impart to understanding to non-experts. When mounting a hanging scroll in Japan, three types of “washi”, Japanese paper are layered. Also, to apply those papers, wheat starch is mixed with water and heated until it is gelatinized and used as an adhesive agent. Further, to increase flexibility, wheat starch paste has been stored in a cool dark place for about 10 years. We were able to conduct a new method of three-dimensional motion analysis on traditional techniques in this research, and investigated whether this leads to better education of the non-experts. We have confirmed that results of the motion analysis that visualize the postures during the operation have had a positive influence on the non-expert.

    In this study, we analyze the techniques of experts and non-experts as a hairdresser and compared their skills based on eye tracking technology. The first purpose of this research is to clarify the differences between the beauty skills of experts and non-experts. The second purpose is to provide the findings to assist in the development of building educational programs for beauty skills of non-experts. In this study, the characteristics of experts were indicated based on video recording, eye tracking technology, and interview survey from experts.

    In this study, the skill of automotive engineers in sheet metal repair is analyzed. Because no two damage situations are identical, every damage is reconsidered on a case-to-case basis, and flexible responses are required. This work requires considerable human technical skill and relies on experienced workers. When the skills depend on experience, human resource development is essential to impart such skills. The overall objective of this research is to propose a personnel training tool. The fender of an automobile was repaired by workers by a sheet metal working technique. The results showed that the experts initiated their strikes in the peripheral part of the dents. Thereafter, they applied several broad strike patterns in their repairs: for example, avoiding striking the peripheral part of the dent; striking the central part while avoiding the press line, followed by striking both the peripheral and central parts; and applying many strikes on the press line in the central part of the dent.

    自動車修理における塗装技術者には高い技術・技能が求められるが、熟練技術者の技が誰にでも分かる形式値として広く知られているとは言い難い。そこで本研究では、3次元動作解析装置を用いて、熟練技術者のドアパネルへのブロック塗装におけるスプレーガンの扱い方を明確化することを目的とした。技術者がスプレーガンの操作条件の選択を行える「吹き付け距離」、「吹き付け角度」、「運行速度」、「塗り合わせの間隔」の4項目に着目した。本報告では「吹き付け角度」、「塗り合わせの間隔」の結果を示し、先行研究にて示した「吹き付け距離」、「運行速度」の結果を交え、既刊の塗装マニュアルとの比較・検証を行った。この結果、熟練者はドアパネル上部、中央部、下部のそれぞれの部位において、ドアパネルの面に垂直に塗料が吹き付けられるように、スプレーガンのノズルの向きを変化させ、約40mmのノズル間隔で塗り重ねていることがわかった。

    The repair of a damaged car doesn't have the same situation. The repair of a damaged car needs individual way and work by hand. It's necessary to advance work for the car repairing engineer with progress of automotive material. An analysis of car repair expert's motion plays the important role in craftsman upbringing. Therefore, the goal of this study is development of the learning system for car mechanics using analyzing the technique of the craftsman. In this study, the hitting motion by hammer of expert's sheet-metal molding process for automobile repair were analyzed and compared with those with non-expert. As a first step, this paper intends to clarify the characteristic motions of experts. We measured the motions of the skilled and unskilled during car repair the sheet metal molding using the 3D digital motion analysis equipment, and then analyzed the results.
