When and where did it act? At present, the position of the metal plate strip with the out-of-tolerance thickness is judged by eyes of an operator, then the machine is stopped, a micrometer is used for rechecking whether the out-of-tolerance thickness exists, and finally whether the cutting is carried out or not and how much the cutting is carried out are determined. Therefore, manual judgment is time-consuming, labor-consuming and fuzzy, erroneous shearing or non-shearing, excessive shearing or less shearing are caused by erroneous judgment, namely, materials with over-thickness are not cut off separately, materials with qualified thickness are cut off separately, and the erroneous shearing or the non-shearing are caused.
