Abstract--Vibratory bowl feeders are commonly used in automated assembly systems to feed and orient variety of engineering parts. Vibratory bowl feeder mainly consists of a bowl connected to a base by three or four inclined leaf spring. Feeder causes a coupled rotation around its vertical axis due to constraining of the leaf spring. The feeder is activated by electromagnet.The investigation proposes the development of a model that predict 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 vibratory bowl feeder.In this paper,the developed model can used to reduce the noise; nonlinear motion of the partsand to improve the feeding efficiency. The model has been verified by means of modal and harmonic analysis and validated throug
