Whistling Noise

This work deals with the noise generated from sawing processes of medium density fiberboard, where special attention was given to the changes in sawing noise at different cutting conditions when using circular saws with varied radial slots. The experimental results gave the following insights: The noise level in idling is positively related to the spindle speed. According to the noise power spectra, whistling noise is found during sawing processes, which is mainly caused by self-excited vibration of saw, and it had directivity. Furthermore, the radial slots have a different positive contribution to the noise reduction during idling, but has limited effect on the noise in cutting. In order to reduce the noise pollution induced by sawing, it was proposed to use circular saws with radial slots and copper plugged in its bottom for sawing of medium density fiberboard, in respect to low noise level and avoiding whistling noise.

Composite Reinforcement

Thinner saw blades cannot resist large lateral cutting forces due to their lower stiffness. In this paper we propose a composite reinforcement method to improve the mechanical properties of circular saw blades. We analyze and simulate the stress and strain fields of our proposed reinforced circular saws by Finite element method. Our analytical results contain not only influences of reinforcing parameters but also loading conditions on the lateral stiffness and the natural frequency of composite saw blades. Here the reinforcing parameters include: 1) the reinforcement location on circular saw blades, 2) the volume fraction of the reinforcements, 3) the number of the reinforcements; and loading conditions include: 1) the cutting force, 2) the rotational speed. Our composite reinforcement model and simulation results can contribute to a better design of circular saw blades.

Random Vibration Analysis

Two types of flow-induced vibrations in idling circular saws, random vibration and resonant vibration, were modeled and analyzed. The excitation source, which is the flow pressure fluctuations, was modeled as discrete forces acting at the saw teeth. The response was assumed to be uncoupled from the excitation in the random vibration analysis but coupled with the excitation in the resonant vibration analysis. The random vibration was solved in terms of statistical rms amplitudes and the resonant vibration as a time function. The analytical results captured many characteristics of vibration phenomena observed in idling saw experiments.

Element Method

The natural frequencies of circular saws limit the operating speeds of the saws. Current industry methods of increasing natural frequency include pretensioning, where plastic deformation is induced into the saw. To better model the saw, the finite element model is compared to current software for steel saws; C-SAW, a software program that calculates frequencies for stiffened circular saws. Using C-SAW and the finite element method the results are compared and the finite element method is validated for steel saws.
