Abstract：A rolling method based on value adjustment is proposed to solve the problem of coil cutting with deficets in manufacturing industry.Under the condition that the specified quantity of rectangular blank is satis－fied, by adjusting the value coefficient of different types of blank , and using the integer programming model to make reasonable arrangement on the defective coils , the blank arrangement is non －interference and can be or－thogonal rotation arrangement , so as to ensure the maximum utilization of resources.Two experiments show that this method proposed has greater feasibility and simplicity.Numerical study shows that the method proposed in this paper can not only solve the coil cutting problem with defects , but also effectively improve the material utili－zation rate.
