Vibrations are inevitable and undesirable for structures in order to achieve stability, durability, performance and quality. Reduction in vibrations can be achieved by increasing the damping ratio or by increasing the stiffness of the structure. In a boring operation, the boring bar deflects due to the tangential and radial forces acting on the tool. The major force acting here is the tangential force. This force increases when the boring bar is clamped at longer overhangs causing deflections. Conducting an analysis on the boring bar is the aim in the project with and without reinforcement to achieve set of optimized parameters given from Taegu Tec, Bangalore. Vibration reduction is a challenge and working on the analysis made it interesting for my selection of the project.
The aim of the project is carrying out a comparative analysis and optimization of machining parameters of two boring bars of diameter 40 mm with and without reinforcement. Tungsten carbide is used as the reinforcement. To conduct the analysis, two static tests and a dynamic test is planned for the project at diff
