Comparison of Natural Frequencies Values of Circular Saw Blade Determined by Different Methods

Research subject and fields:

In most cases high cutting speed is used when cutting wood by circular saw. This results in oscillating of circular saw blade, which may lead to destroying the tool, machine or hurting the operator. The aim of this paper is to show that it is possible to apply any of the methods used in the research as an equivalent method for obtaining the values of natural frequencies of circular saw blade. The article deals with three methods for obtaining the values of natural frequencies. The first method is modal analysis, the second method is the determination of values measured experimentally and the last method calculates the values by Bessel functions. A circular saw blade was used with the diameter of 350 mm and 36 teeth on the blade.
