Vibration Analysis of Circular Tile Cutter

Circular annular cutters with uniform radial cracks are extensively used in the cutting processes. Unwanted noise, vibration & accidental failure associated with the cutting process have become an important economic and technological problem in the industry. The knowledge of natural frequencies of components is of great interest in the study of response of structures to various excitations. Hence, it is important to study a circular plate cutter with central hole, which fixed at inner edge and free at outer edge with its dynamic response. In this study some efforts are taken for analyzing vibration characteristics of annular disk cutter used in tile cutting industries with free boundary condition but having different (numbers of cutting teeth's, aspect ratio, effect of different slots, variable radial slit, circular concentric slit). From the FFT experimentation and FEM validation results, it is found that this study is needful for design data preparation. Secondarily, modal analysis is one of the better tools for finding vibration characteristics for such components. Thus theoretical and experimental results obtained are to be compared.
