Abstract
Mass production has eliminated the craftwork from a majority of industries and brought about a revolutionary change. Automation has evolved along the past years and has become much more sophisticated due to continual starvation for quality. Feeders play a paramount role on the production line. The present study employs a full factorial design technique to analyse the effect of various parameters and interactions between them on output feed rate in a vibratory bowl feeder using spherical washer. An empirical relation followed the analysis of the model. Finally the validation of the model reflected the correctness of the experimental results.
