项目摘要

On Wood Craft or Wood Working in Elementary or Junior High School in Japan, each teacher almost instruct school children or student to use an electrical jigsaw under his/her experimental knowledge. They use the wood working machine with no attention. The machines are widely used in the schools because of its easy use. How to use the machine accurately Have been not researched and investigated by technology education researcher and Wood Craft teachers.In this study we aim at the establishment which is how to use an electrical jigsaw and to advance a cutting skill on it. In order to aim that, real time measurement of each finger-pressure and thumb-pressure of jigsaw workers have been done. For the measurement, we manufactured a sensor system for researching a cutting skill on an electrical jigsaw. The use of this system got several knowledge about a cutting skill on it. The results are as follows.1) We got a workers finger-pressure and thumb-pressure exactly at real time.2) The average pressure of thumb and four fingers of left hand of skillful worker in cutting and that of right hand of it are co-operated.We sometimes got the tendency of this co-operation in unskilled workers, and need to analysis of 10 data (8 fingers and 2 thumbs). A standard of workers skill level which we made needs to change according to his/her age. And the system has 2 points. One is that each worker has long time to attach 10 sensors which are very small(3mm×3mm) and thin(0.5mm). The other is that not all the sensors attached fingers or thumbs pushed the material for experiment. To attempt a solution of the points, we will get a glove scan system which is an article on the market. The use of this glove scan system and our sensor system will analysis complex structures of a cutting skill on an electrical jigsaw.

在日本的小学或初中的木工课上，每个老师几乎都是根据自己的实验知识指导学生或学生使用电拼图。他们漫不经心地使用木工机器。由于使用方便，这些机器在学校被广泛使用。如何准确地使用机器一直是技术教育研究者和木工教师没有研究和调查的问题。在本研究中，我们旨在建立如何使用电拼图，并提高其切割技能。为了实现这一目标，对拼图工人的每个手指压力和拇指压力进行了实时测量。为了测量，我们制造了一个传感器系统，用于研究电拼图的切割技巧。使用该系统获得了有关切割技能的几项知识。结果如下：1)我们有一个工人的手指压力和拇指压力完全实时。2)熟练工人左手拇指和四个手指的平均压力与右手大拇指和四个手指的平均压力是相互配合的。我们有时会在非熟练工人身上发现这种合作的趋势，需要分析10个数据（8个手指和2个拇指）。我们制定的工人技能水平标准需要根据他/她的年龄而变化。系统有2个点。一个是每个工人有很长时间连接10个非常小（3mm×3mm）和薄（0.5mm）的传感器。另一个原因是，并非所有的传感器都是用手指或拇指推动材料进行实验的。为了尝试解决这些问题，我们将获得一种手套扫描系统，这是市场上的一种产品。使用这种手套扫描系统和我们的传感器系统将分析电子拼图上切割技能的复杂结构。
