And storing the newly added x formed after the planned blanking into a surplus material inventory table for recording, and fully utilizing and managing the surplus material.
Through the steps, the information of the drawing table and the excess material inventory table is required to be updated in real time after the excess material is discharged, so that the data is accurate, and the use condition of the excess material is better managed and known.
Further, if a, b, c in (a, b, c, d) of the newly added x is equal to a, b, c of the original x in the excess stock table, the newly added x and the original x in the excess stock table are merged to form a row of data, and d of the row of data is the sum of corresponding data of the newly added x and the original x.
In addition, if the values of a, b, and c in (a, b, c, and d) of the new numbers x are equal, the new numbers x can be combined to form a row of data, wherein d of the row of data is the cumulative sum of corresponding data in the new numbers x.

In some preferred implementations, the targeted objects of the remainders can be rods, in particular steel bars and pipes.
In summary, the blanking method has the following advantages:
(1) classify the clout, form multirow data, be convenient for manage the clout to during the unloading, the data of the clout that will unload with need with drawing the table contrast, can know the clout fast and can cut into which kind of materials that need, make the clout maximize satisfy and need the requirement.
(2) When each row of excess materials are blanked, each excess material in each row of excess materials has a corresponding blanking cutting plan, and the number of the required materials which can be cut into the excess materials and the residual quantity after cutting can be obtained through the blanking cutting plan of each excess material, so that powerful guidance is provided for field cutting of workers.
(3) And the excess stock table and the required planning table are subjected to data updating, so that after each excess stock utilization and blanking, the data are clearly and clearly recorded, and the excess stock formed after each blanking is stored into the excess stock table as new data, so that the circulation blanking of the excess stock is realized, and the resources are fully utilized.
It should be understood that the blanking method for the excess material can also perform blanking for the raw material; the clout compares, the raw materials of same type, specification, single long is general all the same to the single long of raw materials is general all to be greater than the material that needs to use, and the radical of raw materials is general sufficient in addition, leads to when utilizing the raw materials unloading, and the unloading situation is comparatively simple, consequently is to the unloading of raw materials to the simple situation application of clout unloading, specifically is:
classifying and recording the raw materials to form a raw material inventory table;
acquiring plan data of materials to be used, and carrying out classification recording to form a planning table of the materials to be used;
according to the raw material inventory table, finding out corresponding data in the required utilization planning table, and forming a required utilization planning array;
planning blanking by using a raw material inventory table according to the required utilization planning array to obtain a blanking planning array of raw materials;
and (5) blanking the raw materials according to the blanking plan array.
The blanking method in the application can carry out blanking on the raw materials after the blanking of the excess materials in the excess material warehouse is finished, can carry out blanking on the excess materials, can carry out blanking on the raw materials in the same way, increases the application range of the method, carries out blanking according to the excess materials in a way of carrying out blanking on each row of data and each column of data, also fully utilizes and records the raw materials, and avoids material waste.
