What are the causes of damage to the high-speed cutting machine? High-speed slitter blade damage and slitter blade wear are also a form of slitter blade failure. When the cutting machine blade is used under certain cutting conditions, if it cannot withstand strong stress (cutting force or thermal stress), sudden damage may occur, causing the tool to lose its cutting ability in advance. This situation is called cutting. The machine blade is damaged. Damage is relative to wear.
        In a sense, damage can be considered an abnormal wear. There are two types of damage to the blade of the slitter: early and late (breakage after processing to a certain time). There are two types of damage to the blade of the slitter: brittle damage and plastic damage. When cutting hard alloy and ceramic cutting machine blades, under the action of mechanical and thermal shock, brittle damage often occurs. Brittle damage is further divided into: chipping, breaking, peeling, and crack damage.
         The forms of blade damage of high-speed slitter are mainly wear and tear. In the modern production system (such as FMS, CIMS, etc.), when the blade of the slitter is abnormally worn or damaged, if it cannot be found and taken measures in time, the workpiece will be scrapped, or even the machine tool will be damaged, causing great losses. Therefore, it is very important to monitor the blade status of the slitter.

        High-speed cutting machine blade damage monitoring can be divided into direct monitoring and indirect monitoring. The so-called direct monitoring means directly observing the state of the slitter blade to confirm whether the slitter blade is damaged. One of the most typical methods is the industrial TV) camera method. The indirect monitoring method is to use other physical quantities or physical phenomena related to the breakage of the slitter blade to indirectly determine whether the slitter blade has been damaged or whether there is a harbinger of the upcoming damage.
