Comparison Between Theoretical, Analytical and Experimental Vibration Analysis Method and Different Circular Tile Cutter by Using FFT and ANSYS

Abstract

Circular cutters with uniform radial cracks are extensively used in the cutting processes. Unwanted noise, vibration and 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 tile cutter with central hole, which is fixed at inner edge and free at outer edge with its dynamic response. In this study, some efforts are taken for analyzing the vibration characteristics of tile cutter used in tile cutting industries with free boundary conditions but having different (enlargement of stress concentration holes, slot end hole diameter, numbers of cutting teeth’s, aspect ratio, effect of number and length of cracks, variable radial slit, circular concentric slit, thickness etc.). Results from the FEA and FFT found that, this study is needful for the design data preparation to avoid resonance and vibration in tile cutting industries from which it can be easily found out the natural frequency and vibration (w.r.t.) the different changes in tile cutter. Thus, theoretical ANSYS and FFT results obtained are to be compared.
