Excess-material-centralizing-oriented rectangular part optimizing discharging method

Abstract

The invention relates to a discharging method of rectangular parts cut on a rectangular raw material, and aims at providing an excess-material-centralizing-oriented rectangular part optimizing discharging method. The method comprises the following steps that 1, a raw material basic information set (M, L, W, S) and a rectangular part basic information set (n, l, w, do) are initialized, and the current part need number d is made to be equal to do; 2, the raw material basic information set (M, L, W, S) is traversed, and a temporary stock layout (j, Ij, Fj, s) is screened out for each raw material based on a stock layout batten optimizing rule; 3, the raw material utilization rate of each temporary stock layout is calculated, the temporary stock layout with the maximum raw material utilization rate is selected out to serve as a preferred stock layout (j, I, F, s), and the remaining part need number dr is calculated to be equal to d-Fl; 4, whether the remaining part need number dr is 0 or not is judged, and if not, d is made to be equal to dr, the step 2 is executed till dr is equal to 0, and therefore a discharging scheme which is composed of the preferred stock layout (j, I, F, s) and meets the target need number do is obtained. On the premise of guaranteeing the high raw material utilization rate, centralizing of excess materials on the raw materials is achieved, and the rectangular part discharging cutting process is simplified.

Description

technical field [0001] The invention relates to a blanking method for cutting rectangular parts from a rectangular raw material. Background technique [0002] In rectangular parts manufacturing enterprises, rectangular parts are produced and processed in batches in the form of installation orders. The blanking and cutting of rectangular parts belongs to an on-line staged manufacturing process. In each manufacturing stage, the blanking and cutting of rectangular parts will produce a certain amount of residual material. The size and shape of the residual material area determine whether it can be processed secondary use. In the existing technology, each manufacturing stage only takes the maximum utilization rate of raw materials as the production target. After the rectangular raw material is cut and processed, many scattered small pieces of rectangular residual material will be produced. Utilization, can only be disposed of in the form of waste. For the continuous production...

Problems solved by technology

In the existing technology, each manufacturing stage only takes the maximum utilization rate of raw materials as the production target. After the rectangular raw material is cut and processed, many scattered small pieces of rectangular residual material will be produced. Utilization, can only be disposed of in the form of waste

For the continuous production and processing of rectangular parts, the phenomenon of residual material fragmentation will cause potential and continuous waste, which will affect the direct economic benefits and sustainable development of enterprises.
