Determination of burr thickness in high-speed cutting of pipe bundles with circular saws

摘要

The method of high-speed cutting of cold rolled steel with circular saws is one of the most common in modern mechanical engineering. But often, cutting cold rolled metal is accompanied by the formation of a burr at the ends of the blanks. This machining method is characterized by high productivity, significant tool wear and intense heating of the workpiece due to high cutting speeds. The thickness of this burr is directly dependent on the pipe material, the temperature in the cutting zone and the saw feed. The article proposes a mathematical relation to determine the thickness of the burr by these parameters.
