FINITE ELEMENT ANALYSIS OF CIRCULAR SAW BLADE AND STRESS REDUCTION BY USING SURFACE COATING METHOD

Abstract

Circular saw blade in machining industry undergoes different cutting forces during machining of different materials. To analyze the effect of these cutting forces finite element analysis of the saw was done to calculate the stresses in hypermesh. This paper involves the analysis of the circular saw blade in Ls Dyna a module of Hypermesh. LS-DYNA is a multi-purpose, explicit and implicit finite element program used to analyze the nonlinear dynamic response of structures. For this analysis four specimens of different materials are used. The stresses generated after the analysis is compared and then the maximum value is noted. The circular saw is then coated with three different materials namely titanium TiC, TiN and Al2O3. Then the specimen who’s cutting generated maximum value of stress in the circular saw blade is again cut by the coated circular saw blade. Then the stresses are again calculated and compared and the coating which reduces maximum stresses is selected.
