On Development of Testiiig and Traimiig Device forTechnical Background and Ability of Engineering Students

在这项研究中，它表明，测量手掌和手指的力的变化，在工作中，以锯切割木制工件与工科学生的技术背景和能力有关。根据这一观点，研制了一种技术背景和能力测试训练装置。通过专家、熟练使用者和初学者用手锯切割试件的试验，得到以下结果：（1）工程师使用手锯的技术水平与手锯在手掌和手指上的力分布密切相关。(2)专家在使用锯时手掌的力变化是有规律的。而初学者则表现为不规则的突变型。（3）参考专家的力模式进行的初学者训练的次数提高了他使用锯的力变化和技能水平。（4）所提出的装置可用于测试和训练工人在使用手锯进行切割期间的技能。

In this study, it is shown that a measuring force variations of the palm and fingers during working to cut a wooden work piece with a saw is related to the technical background and ability of engineering students. According to this stand point, a testing and training device for the technical background and ability is developed. Some testing has done for cutting the test piece by the expert, the good user and beginners with a hand saw.Results obtained is as follows ;(1)The technical skill level of a engineer for the using a hand saw is closely related to the force distribution in the palm and fingers.(2) The force variation in the palm of the expert during using a saw changes regularly. However, it of t he beginner shows a irregular and suddenly changing one.(3)Number of training for beginners which is done referring to the force pattern of the expert improves his force variation and skill level in using a saw.(4)The device proposed is useful for testing and training the skill of workers during cutting by using a hand saw.
