An Approach to Detecting Tension of a Circular Saw

This paper discusses the approach concerning the detection of the tensioning of a circular saw and the implementation of its system.The parameters for the three following features demonstrate the tension distribution and levelling of a circular saw. The variations of natural frequency before and after a saw blade being tensioned, the transverse deformation of the saw blade under one spot being loaded and the run -out of the saw blade have been taken into account. The experiment shows that this approach is feasible, through the application of the above-mentioned detecting system controlled by the computer to test dozens of different-sized circular saws for wood cutting and large -sized circular saws for stone cutting.
