DEVELOPMENT OF PRODUCTION

STANDARDS IN THE MELTING LINERS

INDUSTRY

The authors of this QUEST presentation worked with supervisor at a local manufacturer, Fireline. This study was done for credit in the methods engineering

class as a part of the Industrial and Systems Engineering program. Motion and time study analysis were performed using the techniques of video capture of the process, analysis of the fundamental motions and establishment of standard times using both classic and predetermined time study procedures. Work sampling techniques were used to help characterize the non-repetitive work content associated with a highly

coupled man-machine process. The analysis that was done on the subject and the surrounding operations were characterized through methods engineering tools, such

as, man-machine process charts, flow charts, and plant diagrams.

TIME STUDY DATA

SUMMARY OF TIME STUDY

A graphical display of time spent for each from the Time Study Data displays the operator spends a fair percentage of the time scraping.

Standard TimeST= NT x (1 + Allowance)ST=(107.83) x (1 + (.12))ST=120.77 sec

**In a normal 8hr work day each worker should be expected to produce about 210 liners each day.

SUMMARY OF TIME STUDY

OPERATOR PROCESS CHART

This chart shows all movements of the process made by the left and right hands and the relationship between them. This chart facilitates changing method so that balance two-handed operation can be achieved for a smoother rhythmic cycle and keeps the operator fatigue to a minimum.
