Problems solved by technology

[0003] When monitoring existing machine tools, half of them monitor whether their electrical signals are normal, which is generally judged by setting a threshold. However, the signal sizes of different products are not the same, so the threshold setting will be much higher than some Products, at this time, if there is an error in the machine tool during the production of these products, the conventional electrical signal detection cannot detect the problem
