Abstract: The paper proposes introducing a new operation to reduce rejections in a recognised automotive industry. This industry manufactures cylinder liners by using the updated technologies & principles in the market. The problem lies in the operation process i.e., when machining due to compressive and shear forces by the tool on the liner , residual stresses are developed in the beneath the collar of the liner . The liners are passing the quality inspection but when the liner goes to assembly section at the customer end it fails by developing a crack beneath the collar. The main objective of this paper is to reduce the rejections for that particular reason in the cylinder liner manufacturing industry. This can be done by application of introducing a new operation in the process named deep rolling. By performing this operation the inner grains of the liner at that particular area will be aligned by the concept of cold strengthening & burnishing.
