A Time-Motion Study by Methods of High-Speed Cinematography

In this paper an attempt has been made to evaluate a method of motion study pertaining to moving machinery. The test object was a 13-ton capacity punch press and the motion study was performed with a high-speed motion picture camera. It is shown that the motion picture camera produces: (1) a visual indication of the actual occurrence which allows an understanding that nonvisual means could not afford; (2) a method of study which does not influence the system studied in the least; and (3) a record of the occurrence which has very little inherent error.
