过去我厂的钢材是分散下料。材料放在车间里,保管员到月底的时候索要领料单,车间用多少是多少,至使下料中的非工损耗高达13％左右,材料浪费很大。针对这种情况,从1984年5月起,我厂实行了限额供料,使下料非工损耗降到了7％左右,但由于在旧的下料方式的影响下,钢材集中下料的优势还没有充分发挥出来,影响了钢材利用率的进一步提高。为此从1986年开始实行排料图下料的新方法。排料图下料新方法,就是在一块有限的钢板上,对同材质同规格的大小零件合理搭配,先画出排料图,用排料图指导划线,指导切割下料。这样改变
In the past, the steel of our factory was dispersed and unloaded. The materials were placed in the workshop. When the custodian arrived at the end of the month, they asked for a picking list. How much was used in the workshop, so that the non-working loss in the cutting was as high as 13%, and the material was wasted. In view of this situation, since May 1984, our factory has implemented a limited supply of materials, so that the non-work loss of cutting down to about 7%, but due to the impact of the old cutting method, the advantages of steel concentrated material Has not fully exerted, has affected the further increase of steel utilization rate. For this reason, from 1986, a new method of unloading of discharge markers was introduced. The new method of material discharging is to match the same size and size of the same material on a limited steel plate. Draw a discharge pattern first, use the discharge pattern to guide the line, and guide cutting and cutting. This change
