Predicting reliability has become an important engineering science and involves complex mathematical relationships and calculations. The reliability of an automated high-speed production line with all its complex mechanical and electronic components is also important, as its failure can result in major economic losses to the manufacturer. This paper reviews about the emphasis of reliability engineering on the feeding system and element in automatic machines. It also discusses about the calculation of the reliability parameters on the feeding unit by applying the probability theory. Various formulae and derived to calculate the limit size or the chute width and probability or the part sticking into the shut. Besides, a case study has undertaken to calculate the value of probability.
