[0104] Step S355: Determine whether the material thickness influence value is greater than the interval deviation reference influence value. If yes, execute step S356; if no, execute step S357.

[0105] Among them, by judging whether the material thickness influence value is greater than the interval deviation reference influence value, it is judged whether the thickness adjustment value has a positive impact on the middle value of the adjustment interval.

[0106] Step S356: Calculate the sum of the middle value of the adjustment interval and the thickness adjustment value and use it as the adjustment selection value.

[0107] Among them, when the material thickness influence value is greater than the interval deviation benchmark influence value, it means that the thickness adjustment value has a positive impact on the middle value of the adjustment interval. Therefore, the sum of the middle value of the adjustment interval and the thickness adjustment value is calculated and used as the adjustment selection value, thereby improving the accuracy of the obtained adjustment selection value.

[0108] Step S357: Calculate the difference between the middle value of the adjustment interval and the thickness adjustment value and use it as the adjustment selection value.

[0109] Among them, when the material thickness influence value is not greater than the interval deviation benchmark influence value, it means that the thickness adjustment value has no positive impact on the middle value of the adjustment interval.

[0117] Step S420: Determine whether the position deviation is less than the reference displacement. If yes, execute step S430; if no, execute step S440.

[0118] Here, whether to directly perform the initial waiting is determined by judging whether the position deviation is smaller than the reference displacement.

[0119] Step S430: using the operation initial control information as the operation follow-up adjustment information.

[0120] When the position deviation is smaller than the reference displacement, it means that the initial waiting is directly performed at this time, so the operation initial control information is used as the operation follow-up adjustment information.
