Design, Analysis and Manufacturing of Fin cage Component Used in Missile

Author(s): Thunugunta Sai Kumar, Y. Venu Babu
Abstract: In the context of modern and fast emerging industrial world, technology and automation is considered to be a big boon for the fast and rapid industrial development. The main objective of today’s industries is to maximize the production within the stipulated time using an optimum amount of man power and resources. The trends which accounts for today’s technological development includes CNC machining, DNC, FMS, CAD/CAM etc. rnFin cage is used to hold the fins of the missile in folded condition while it is enclosed in launch tube. When the missile is fired, fin cage travels along with the missile, holding fins and gets strucked at the front end of the launch tube, so that the fins gets opened and guides the missile when it just crosses the launch tube.rnThe dynamic characteristics analysis of Fin cage is mainly involved in the calculation about vibrations on model. The objective to calculate the vibrations and resonances of Fin cage is modulating those frequencies and avoiding resonance, thus the vibrations of Fin cage may reduce. rnThis project also deals with development of manufacturing process plan of missile component (FINCAGE used in missile) using CAM software (NX 7.5) which is exclusively CAM software used to generate part program by feeding the geometry of the component) and defining the proper tool path and thus transferring the generated part program to the required CNC machine with the help of DNC lines. The operator thus executes the program with suitable requirements. The component requires both inside and outside machining. So it needs a special type of fixture to hold the component rigidly. As the component involves thin walled lugs, for machining and dimensional accuracy it calls for CNC machining. Because of such reasons it is very difficult to get high surface finish and reducing the machine utilization without doing the process optimization.rnIn this project, the 3d model of Fin cage is designed in UNIGRAPHICS software and it is imported to ANSYS software to perform the dynamic analysis. Then efforts are made to produce different process plans in CAM software by changing the work holding systems, tool paths, cutting tools etc. Finally, recommending an optimum process plan for manufacturing of the component.rn
