Analysis on the Three-Dimensional Wire Orientation of ‘Kana-Ami’ Metal Network Between Expert and Non-Expert

As well known, Kyoto has been the capital city of Japan for one thousand years. The long ancient culture brings out a serious of traditional craft products, such as ‘Kana-ami’ — a kind of metal wire network. ‘Kana-ami’ was all made by hand work, for this reason there was no industrial pollution produced during the manufacturing process. In other words, ‘Kana-ami’ is a kind of green manufacturing product, and its processing motion and working experience make a big effect on final products’ quality. Product’s quality was judged by the standard structure of ‘Kana-ami’, which was established after a long period of history and culture accumulation. That aesthetical standard has already been consistently rooted into Japanese peoples’ heart deeply. Dated back to around 50 years, there were about 30 handmade wire net shops in Kyoto. However, it has decreased dramatic until 7 shops now. Therefore, it is urgent time to pay attention to this severe reality and try to do something to keep this traditional culture wealth and continue green manufacturing technique and skill to the next generation. In this study, the expert and non-expert were employed as the target investigated subject from ‘Kanaami Tsuji’ workshop. Investigated subjects were required to fabricate a Kana-ami product, which was investigated by 3D motion capture during product’s fabrication. The structural features of final products by expert and non-expert were illustrated and compared by the numerical analysis. The moment of scoop tofu was recorded by high-speed camera in order to clarify the small differences on product performance. In a word, the great effort is to reduce the final products impact to the surface of tofu.
