工作機械作業における能動感覚フィードバック

微細加工作業における切削力の視覚フィードバックの効果

In manual machine operation, human operators could perform their task well and swiftly, if they could acquire sensory information helpful to the performance effectively. In this research, the effectiveness of active visual feedback has been investigated. As the feedback devices, two kinds of head mounted display (HMD) and LED array have been examined. The objective operation is to make a small-diameter hole onto an aluminum workpiece with a carbide drill and the feedback information is cutting force. The information has been given to the operator by geometrical charts in HMD and by brightness change in LED array. As the results, the see-around see-through type monocular HMD is superior to the see-through type binocular HMD as the visual feedback device, because the former can give wide eye sight to the operators. In addition, the geometrical charts are superior to the luminance change in improvement of operating efficiency and reduction of workload. Among the geometrical charts examined, sector chart is more effective than bar chart.
