The vibratory bowl feeder is used in automated assembly to sort and orient a variety of parts. To design a part feeder the engineer needs knowledge related to the tendency of the parts to fall in different aspects and production requirements. The investigation proposes the development of a model that predicts the influence or the effect of the vibration amplitude in the orientation efficiency. The model was based on the identified parameters, such as part’s geometry and orientation, to optimize the design and performance of the vibratory bowl feeder. In addition, experiments were conducted using five different parts in the bowl feeder to estimate the probabilities that the parts have when resting in all possible aspects while moving through a surface in movement. These experiments provided information that will help in the development of the model. The results were compared with the method of the centroid solid angle and the stability method, and a good correlation was obtained.
