### Development of production standards in the melting liners

1. 1. The authors of this QUEST presentation worked with supervisor at a localmanufacturer, 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 theprocess, 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 throughmethods engineering tools, such as, man-machine process charts, flow charts, and plant diagrams.

4. 4. 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.Left Hand Description Symbol Time Time Symbol Right Hand DescriptionGrab Part RE/G 3.223 3.223 RE/G Grab partSet Part Down M/P 1.596 1.596 M/P/RL Set Part DownTurn Liner H 14.33 2.548 RE/G Grab Knife 8.858 U Scrape 1.218 RL Put Knife Down 0.306 RE/G Grab Blowing Tool 1.1 U Blow 0.3 RL Put Blowing Tool DownGrab Finished Part G 1.501 1.501 RE/G Grab Finished PartPlace Finished Part M/P/RL 1.356 1.356 M/P/RL Place Finished Part
