摘要: 为提高柔性数控单元生产效率,提出一种基于工序平衡的高柔性数控单元调度方法。第一阶段,根据产品生产工艺和设备生产能力进行工艺路线规划,在考虑生产约束、生产准备时间、工艺柔性和设备产能的基础上,构建产品节拍平衡优化目标,获得其最优加工视图组合;第二阶段,基于工序平衡的结果,在考虑产品换线时间的基础上构建整单调度模型,并采用遗产算法求解。最后,将所提调度方法在某壳体产品高柔性数控生产单元进行应用研究,并与分批量调度模型进行了比较分析。研究表明,所提出的工序平衡的柔性数控单元整批量调度方法可以有效缩短单元的制造周期,提高单元控设备利用率。

Abstract: To promote the performance of production, and enhance the machine utilization ratio, a scheduling method based on balancing takt of high flexibility numerical control manufacturing cells is proposed. First, the process planning is established on the basis of process characteristics and equipment capacity, then the balancing takt as optimal processing views combination is achieved on the basis of considering the preparation time, machine capacity and processing sequence. Second, the product scheduling models which considered the product changeovers time is proposed based on balancing takt result, and then a genetic algorithm is proposed to solve the model. Finally, a shell numerical control manufacturing cell is provided as example, and a comparative variable batch scheduling model and two-stage scheduling based on balancing takt is conducted. Study identified, two-stage scheduling based on balancing takt can significantly reduce the production cycle and promote the performance of numerical control machine.
