Sažetak
It is well know that the behavior of wood material deviates from generally used engineering materials since wood is anisotropic material with viscoelastic properties which have highly aggravated derivation of generally valid relationships. Machining usually alters the shape, size and surface quality of wood. In most cases wood machining occurs by cutting and the chips are the by-product which can be used for chipboard production or to generate energy. Heat generated by wood cutting is caused by friction between cutting tool and wood. This heat can have negative influence on tool because it causes tool wear so extensive research is required. In this paper the results of investigation of geometry, rotational speed and heat generated by wood cutting on vibrations of circular saw blade are presented [1]. First the analytical method for determining the natural frequencies of annular plates is used and compared with FEM models of annular plates and circular saw blades [2]. The influence of slot shape and rotational speed on vibrations of circular saw blade was investigated using FEM method. Based on previous research [3] and [4] the heat generated by wood cutting is calculated and used for numerical analysis using FEM method. Besides heat the effect of slot length and rotational speed on vibrations of circular saw blade was investigated.
