In machining fixtures, minimizing work-piece deformation due to clamping and cutting forces is essential to maintain the machining accuracy. The various methodology used for clamping operation used in different application by various authors are reviewed in this paper. Fixture is required in various industries as per their application. This can be achieved by selecting the optimal location of fixturing elements such as locators and clamps. The fixture set up for component is done manually. For that more cycle time required for loading and unloading the material. So, there is need to develop system which can help in improving productivity and time. Fixtures reduce operation time and increases productivity and high quality of operation is possible. This paper introduces the new techniques to achieve the complicated operations done with the help of fixtures. The complex structures like obtaining the cylindrical shape from a rectangular workpiece. This type of operations generally performed on the 5-axes or 6-axes machine. This fixture can provide the more advanced features by which it can facilitate the complex operations. There are various complex shapes that can be obtained on the 3-axes machine with the help of this fixture. There will be no need of 5-axes or 6-axes machine to perform such kind of operations. The production cost can be minimized relatively the selling cost of the product will be competitive in the market. The computer-aided structural analysis and simulations have been performed to study the stress and deformation of mechanical components in assembly process. The design of the fixture is done on the Cero 2.0. The validation of the design is done on the ANSYS workbench 16.0. There are various stresses acting on the fixture in different directions. The factor of safety kept as high as possible. The model analysis is carried out to keep the vibrational stresses in control and this is achieved by selecting proper material which will have the good damping capacity. The computer-aided simulation demonstrates close results that present the feasibility and reliability of this newly designed and developed mechanical system for Automobile Industry.
