Motion Study
A Method for Increasing the Efficiency of the Workman

INTRODUCTION xix box. The time study of this job revealed several inter- esting facts. First, after the piece was drilled the machine was stopped, and time was lost while the workman removed the piece from the jig and substituted a new one. This was remedied by providing a second jig in which the piece was placed while another piece was being drilled in the first jig, the finished one being removed after the second jig had been placed in the machine and drilling started. It was also found that the workman lost considerable time hunt- ing in the tote box for his drill, and for the socket to fit it. The result was the provision of a socket for each drill, which was fitted to it in the tool room, and the further provision of a tray alongside the machine on which the man could lay out his drills in the order in which they were to be used. He was thereby enabled to pick up the correct drill without losing any time hunting for it. It was also found that it took considerable time to verify the size of the drill and socket, due to the figures stamped on the drill by the manufacturer being so small as to require the workman to go to the light to hunt for the figures. Consequently, numbers one-half inch high were placed on the drills, so that they could be seen in almost any light. To do this it was necessary to grind a flat spot on the drill to accommodate the large-size figures. This had the desirable but unsought for result of enabling the work- man to locate the figures by the sense of touch, and con- sequently no time was lost in turning the drill round and round to search for the size.
