- Opis:
- Oscillation is an unwelcome state as it has adverse effects not only on the work piece but also on the tool. This paper deals with the problem of circular saw blade oscillation and the effect of modification of the circular saw blade body on the natural frequency as well as on the critical rotational speed. The calculation and experimental investigation of the natural frequencies and node shapes on two types of circular saw blades were carried out. Two methods used to determine the natural frequencies are presented: the first, modal analysis (FEM), a theoretical method, and the second, experimental measurement. The results of the investigation were used to compare the FEM and experimental methods and to show which modification achieved a higher critical rotational speed. Both methods were conducted on two circular saw blades for continual cutting with 36 teeth and slots.
