Stress analysis of the rotating circular saw blade

Abstract

The article deals with the determination of parameters of longitudinal wood cutting by circular saw blade and construction of the cutting tool. A computational model was chosen to determine stress of the rotating circular saw blade. Stress analysis revealed that maximal stress caused by the temperature gradient was approximately ten times higher than the maximum stress extrapolated from centrifugal forces. In this work were determined the critical speed of the circular saw blade and the power needed to spin. The contribution of this work is the algorithm of the power required for longitudinal wood cutting wood by a circular saw blade, which allows optimal machine tool proposal. Moreover, the calculated state of stress is compared to the FEM model.
