Applied Motion Study
A Collection Method to industrial Preparedness

CHRONOCYCLEGRAPH DEVICES 91 corded by the stretched cyclegraph, which allows of the various lines recording habit being re- corded accurately, yet in such a manner that they are easily distinguished from one another. These aspects of the motion models are important to the engineer in so far as he is a teacher and in- terested in the learning process. Of perhaps greater importance, however, here, is the motion model as a means of devising, main- taining and improving standards. Through the study of the motion path, either as shown in the chronocyclegraph or in the chronocyclegraph motion model, and through a comparison of such graphs or models showing the paths of different operators doing the same kind of work, it is pos- sible to deduce the most efficient method and to make this a standard. Moreover, each standard motion path is a help towards deducing other standard motion paths. Through an intensive study of motion paths followed in doing differ- ent kinds of work efficiently, there has come a recognition of the indications of an efficient mo- tion, its smoothness, its lack of hesitation, its reg- ular normal acceleration and retardation and its use of habit. The efficient method having been
