In all kinds of Sheet Metal Processing, materials are the foundation and one of the costs, so we must pay attention when calculating to avoid waste. It is a sheet metal processing factory that has been providing customers with a variety of sheet metal processing products for many years. Whether it is materials or processing technology, we strive to achieve perfection. The following sheet metal processing manufacturers introduce the necessity and method of formulating sheet metal material consumption quotas. 1. The necessity of formulating material quotas (1) Material quotas are an important basis for calculating material demand and forming material demand plans. The material supply plan of a manufacturing enterprise is mainly determined by calculating the demand for various materials according to the production tasks during the planning period and the quota of unit products, and then considering the resource situation of materials. Therefore, if there is no quota, the procurement plan indicator will lose its basis, and it is impossible to prepare a correct material supply plan; (2) Material quota can effectively organize quota delivery and supervise the use of materials. With quota standards, materials can be supplied regularly and quantitatively according to the production progress. And in the production process, the consumption situation is effectively controlled, the material consumption situation is supervised, and material waste is eliminated. 2. Determination method of material consumption process quota (1) First, according to the net weight of parts and parts processing technology in the product drawing, as well as the standard requirements of the company‘s material specifications, the economical and reasonable discharge is carried out, and the result of discharge (utilization rate of blanking) is evaluated and optimized, and the layout method and material specification parameters are determined; (2) Determine the material consumption process quota of various unit parts. After the blank is arranged, the remaining edge material is allocated to the total number of dischargeable parts, plus various process losses, which is the part consumption process quota. Process quota = blank weight + edge weight/number of dischargeable blank pieces + process loss, material cutting utilization rate = (part blank weight, part quota) 100% material utilization rate = (part net weight/part quota) 100%
