Cutting system play very important role in marble cutting industry.Circular tile cutters with uniform radial cracks are mostly used in the cutting processes. Cutters are used to cut respective material to a required size or shape . They come in a number of different forms , from basis manual devices to complex attachments for power tools. Unwanted noise , vibration and accidental failure associated with the cutting process have become an important economic and technological aspect in the industry. The knowledge of natural frequencies of components is of great interest in the study of response of structures to various excitations . In this study natural frequencies will be evaluated in desired frequency ranges of cutter mechanism. Mode shapes at various natural frequencies will be evaluated using FEA and FFT results , CATIA V5 software will be used to design various existing blades and modification will be carried out as per results. Optimization to minimize the weight of circular tile cutter and therby reducing the material cost. Optimised model is further verified by FFT and thermal analysis.Conclusion and future scope will be suggested.
