Description

technical field [0001] The invention belongs to the technical field of grinding processing and engineering testing, and in particular relates to a method for machine learning identification and process parameter optimization of abrasive belt wear. Background technique [0002] With the development of machinery manufacturing industry, abrasive belt grinding has become one of the effective methods for precision machining, and abrasive belt grinding has also been used more and more widely. However, in the process of abrasive belt grinding, the abrasive coated on the surface of the abrasive belt rubs against the surface of the workpiece, plowing and cutting, and continuous fracture and wear. The wear process can be divided into crushing wear, abrasion wear and clogging adhesion. . The wear and tear of the abrasive grains of the abrasive belt is caused by the friction between the abrasive grains and the workpiece when they move relative to each other, just like the tip is ground...

Problems solved by technology

However, so far, no relatively mature detection method has been popularized and applied in actual production, and the above method is proposed for the grinding wheel. The abrasive belt is a flexible grinding tool, which is different from the grinding wheel. Many methods are not applicable to the abrasive belt.
