[0002] In industrial manufacturing and processing, cutting is a crucial process. The development of cutting mechanisms has a long history. In the past, manual cutting was common, but this method was inefficient, difficult to ensure precision, and labor-intensive. With the advancement of the Industrial Revolution and the rise of mechanized production, mechanical cutting mechanisms gradually emerged. Early mechanical cutting mechanisms had relatively simple structures and limited functions. For example, the use of simple lever principles or slider mechanisms for cutting, while improving efficiency to a certain extent, still suffered from slow speeds and unstable cutting quality. With the continuous advancement of science and technology, the introduction of electrical control technology has significantly improved the performance of cutting mechanisms. The precise control of motor drives and control systems enables faster and more accurate cutting.
