Abstract—The aerospace component used in this project is a piston ring which is used in rockets. These piston rings are used to release the rocket due to the pressure release in the chamber. These piston rings are in circular-shape that forms the movable seal in a cylinder. The explosive force of combustion is exerted upon the surface of the piston ring. Due to this force the ring deforms and stresses will be created. In this project 3D model of the piston ring and finite element analysis shall be done to observe the deflections and stresses on the piston ring. From the analysis results high stress locations shall be identified and changes shall be made to reduce these stresses. Static and model analysis shall also be carried out on the modified model to find the dynamic behavior of the component. This project also deals with development of manufacturing process plan of piston ring 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. In this project two different manufacturing process plans shall be developed using NX-CAM software and the optimum process plan shall be determined which has less machining time and more surface finish.
