Motion Analysis of Lathe Machining Work Using a Digital Position Display Device

抄録

The ocular movements of skilled and unskilled engine lathe operators were analyzed as a preliminary step in developing a method for supporting the transfer of skills in engine lathe machining. An attempt was made to elucidate the difference in skilled and unskilled workers operating a lathe with a digital position display device (digital readout display meter) that can display the machining status of the workpieces. The impact of the digital position display device was investigated by evaluating and comparing the quality of each production from the operations. In addition, because skillful estimation is necessary for most manufacturing tasks, the differences between the ranges of visual examination of workers were analyzed while a workpiece was being measured.
