Abstract—The current interest in developing a manufacturing capability at the mixed scales is leading to a number of investigations concerned with the development of special purpose machine tools. Competition permanently demands the machine tool manufacturers to improve the working accuracy and the dynamical behaviour of their machines while reducing both product development time and costs. The problem with most special purpose machines is the amount of vibration that is transmitted through the spindle, which affects the quality of surface finish and the dimensional accuracy imparted to the work piece being machined. Owing to the way the spindle is mounted at the end of a cantilevered structure, low resonant frequencies can occur that are easily excited. SPM is a special purpose machine exclusively used in two wheeler automobiles. The main objective of this project is to design and perform finite element analysis of the SPM and make sure that the SPM is free from vibrations. In this thesis design calculations were done using Timoshenko beam theories for different cutting forces. Later a parametric 3D model was developed using the cad software. Both static and dynamic analyses were done using analysis software NX cad software is used for developing 3D parametric model and Ansys software is used for performing static and dynamic analysis.
