The slotted discs are important structural elements in engineering application. The turbine, brake disc and diaphragm clutch spring are the well-known examples of industrial application of annular disc with radial slots. Rotor discs with uniform radial slots are extensively used in the construction of aircraft, ships, automobiles, flywheels, circular saw plates, pressure vessel, missiles, ship structures and liquid containers. The knowledge of natural frequencies of components is of great interest in the study of response of structures to various excitations. Hence one of the application of rotor disc i.e. tile cutter with central hole fixed at inner edge and free at outer edge is chosen and its dynamic response is investigated in this present work. The natural frequencies are detected by hitting the disc with impact hammer; the response at a point is measured with the help of accelerometer. The Fast Fourier Transform analyzer analyzes the response given by accelerometer. The Finite Element Method software package (ANSYS) is used for vibration analysis of tile cutter of the same ratio of inner to outer radius having different number of teeth and different slot end hole diameter with the same boundary condition for determining different parameters such as natural frequency and mode shapes. The analytical and experimental results obtained are compared.
