Abstract
This review paper aims toward the investigation of manufacturing process of hollow cylindrical component to identify the defects causing ovality in circular holes. The manufacturing refers to the processes required to convert raw material into the final product which may include casting, machining, welding, finishing, heat treatment processes and ends with final inspection to check for defects. Mostly the circular holes of hollow cylindrical components show ovality after manufacturing, exceeding tolerance values and such defect leads to poor fittings. After careful study of the variety of research papers related to ovality, it was found that the ovality may occur due to component characteristics or due to defects in manufacturing process of the component. The results of these research papers concluded that machining parameters, unbalanced workpiece, clamping pressure, clamping geometry and clamping technique influence the dimensional deviations and it can be prevented by improving the production with corrective techniques.
