| Research Abstract |
The Grasping feeling tests of cylindrical objects of machine tool handles at positioning by manual control, and sensory evaluation during milling machine operation have been performed. It was conformed that the sensory evaluation for the determined optimum grasping diameter was difficult for children under ten age, because of insufficient growth of the skeltal structure, but that could be determined for parsons above ten. The loading rate for the grasping object increased with increasing the maximum holding force, but with decreasing the optimum grasping diameter. Moreover, the optimum grasping diameter for the holing increased with weighting the object. At the vertical milling machine operation, the larger the diameter of handle, the larger the optimum grasping diameter, but the tendency at having spun a handle was remarkable compared with not having spun the handle. It was found that the smaller handles than 150 mm diameter were operated with a right hand, but that the larger handles than that diameter were operated with both hands. Small handles under 100 mm diameter were operated with the right hand and large handles over 200 mm diameter were operated with the both hand, and the small or large handles were evaluated sensory as comfortable handles for operating. The necessary times for operating those handles were short.
