Description

In this paper, we considered a new tensioning method by the temperature distribution on the base metal of tipped saw. First, the relationship of the temperature distribution on the base metal and the tensioning effect (i.e. transitions of natural frequency) was examined by calculation using a disk model. As the results, when the temperature Θ_c at inner circumference of the disk was higher than the temperature Θ_a at outer circumference, the natural frequency of the two or higher nodal diameters mode increased. And the increments of the natural frequencies were proportional to the temperature deference Θ_c-Θ_a. Furthermore, the tangential residual stress σ_θ at outer of disk had positive value denoted as tensile stress. These results coincided with the effects of the traditional tensioning method so called 'Roll Tensioning'. Then, the validity of the calculation results by experiment using disk was verified. The transition of the natural frequency by the experiments indicated similar tendency to the calculation results.
