[0002] A circular sawing machine is a mechanical device used for cutting materials, and is widely used in multiple fields such as metal processing, woodworking, and plastic processing. The working principle of a circular sawing machine is based on the rotary cutting motion of a circular saw blade. During the cutting process, the circular saw blade rotates at a high speed, and at the same time, the workpiece is fed under the saw blade for cutting. With the rapid development of industrial manufacturing, bars, as one of the important raw materials, are widely used in multiple fields such as metal processing, machinery manufacturing, and construction.
