Abstracts: The final year project is start by the overview of jig and fixture. It is the briefly explanation about the perspective of project namely the jigs and fixtures. List the problem statement that can help to create an idea in order to prepare the solution of all the problems for rectangular and square parts in milling machine. In order to determine the problem statement, the comparison between the milling machine and the lathe machine is needed. This is because both of these machines have significant difference in types of work piece. Cutting tool and machining processes. Need to understand the objectives of this project and make sure the target is achieved. The scope of the project is totally for milling machine so need to give high focus in order to do the fixture design. Besides, need to organize the works into several parts to make sure the works become more systematically. Divided the work into three main parts namely research. Design and Analysis the purpose of this project is to do the case study about fixture for milling machine in perspective of rectangular and square work piece. A new design of fixtures and comes out with the jig and fixture product. Actually, there are many fixtures available in the Manufacturing field so the development a new product of jig and fixture is needed. In the other Hands, this design can improve the ability and characteristic of the milling machine. There is design of fixture for this project. By the design the analysis about the specification, safety factor, characteristic and other factor is needed then select one for the best design. The determination about the suitable material is in producing fixture also important. The result for this project can totally solve the problem for milling machine in perspective of rectangular parts. and This paper is dealing with the engineering design of a gang drilling machine with jig & fixtures to make a prototype machine. This effort has been done in order to solve the problem which aroused in small business enterprises producing birdcages. The problem was how to minimize the production time in making a lot of holes that have same distance and straightness. Hopefully, the prototype machine can help the small business enterprises to increase their production rate. The design engineering process has been carried out by variant approximation on dowel pin modular fixtures in order to simplify fixtures design. CAD CAM software has also been used as fixtures synthesized method including geometric analysis and three dimensional fixtures assembling.
