| 内容記述 | Twenty-two university students performed cross cutting with a saw using two types of auxiliary tools, a developed jig (saw guide) and a mirror for checking the worker's posture. It was verified whether the cut wood was made vertically and accurately according to the marking line. Sawing cutting was performed under the following four conditions, "neither mirror nor saw guide is used (cutting condition A)", "only mirror is used (cutting condition B)", "only saw guide is used (cutting condition C)", "mirror and saw guide are both used (cutting condition D)". The obtained results are as follows: (1) There was no significant difference among the four cutting conditions in the distance of deviation from the marking line on the flat grain surface. Mirror and saw guide could not control deviations from the marking line. (2) A significant difference was found between cutting conditions A and D with a statistical risk rate of less than 0.1% for the angle of deviation from the marking line on the flat grain surface. A significant difference was also observed between A and B, and between A and C, with a risk rate of 1% or less. It was confirmed that even when the mirror and the saw guide were used individually, the deviation angle could be greatly suppressed. (3) Significant differences were found between A and B, A and C, and A and D, with a risk rate of 5% or less for the angle of the edge of board surface that deviated from the marking line. It was confirmed that the deviation angle can be suppressed by using the mirror and the saw guide separately. (4) According to a questionnaire survey after work, the saw guide can be cut more easily than a mirror, and it is safe to cut. In addition, it was found that when they became teachers, they were highly conscious of wanting their children to use the saw guide. |
