This would help to break new grounds in the field of manufacturing and hence enable more efficient use of available resources and also obtain more precise and accurate products.

INTRODUCTION The subject matter of this paper is to present the development and change of Manufacturing Process in different generations.We shall represent various developments and innovations in the time distinguishing different possibilities of growth and research. The processes from the beginning have been divided into various sections and to be specific it is being cleaved into 8 generations with a decade making up a generation.In total 8 generations are illustrated from the origin of production and until the future. We have taken into consider the commonly used methods as the overheads and gave way to branching as the timeline proceeded and approached towards the modern methods.The noteworthy aspect in the content below, is the fact that the new methods have emerged as solutions to some problems faced with the preceding methods.Any succeeding method comes with some advantage in terms of resource utilisation and/or utility. Some of the methods have come to existence in order to achieve highly specific requirements and find less extensive use, however, these cannot be completely done away with.As new materials are being discovered or synthesised and new technologies are being implemented, the sphere of manufacturing processes is also changing its characteristics.Not only are the older root processes undergoing branching, but also some new root processes are coming into existence, which hardly bear much significance with the older processes.This only indicates that the possibilities of the future are endless and this fact is fairly motivating for the researchers in this field of study.
