Abstract: The machine tool industry has gone through tremendous changes since its inception. CNC machine with proper fixtures has the capacity to fill this gap. This has excited this research work on design and development of fixture for CNC. Manufacturing processes are commonly affected by the low stiffness of the components limiting the quality and precision of the final product. Precision is one of the most important issues in the machining process, and the main cause for rejection of the part is due to static deformation and the dynamic vibrations. The static deformation is mainly affected by two factors: deformation due to clamping force, and geometrical distortions due to material removal. This paper presents an analysis to manufacture fixture, using reverse engineering, for sheet metal operation. These fixtures are made by incorporating additional features in the existing fixture to suit for sheet metal machining operation. For design of fixture, computer aided design by Fusion 360 and manufacturing by CNC milling machine is used
