Integrated Machine Grouping, Tool Allocation, and Sequencing in Line Design

生产线设计中的集成机床分组、刀具分配和排序本研究项目为制造工艺规划提供了重要的支持功能。近年来，许多制造商都进行了大量投资，以记录最佳制造实践。由此产生的数据库和知识库提供了一个很好的机会来提供自动化能力，这种能力可以通过对工艺规划问题的严格理解来实现。制造商将通过开发用于自动化和工业数据验证的数学模型和算法来获得竞争优势。该方案考虑了在转移线上生产的复杂零件的大批量生产。在这里，机器是灵活的，能够以可控的速度执行所有计划的操作。当在刀库中分配了不同的刀具组时，机器的能力是不同的。每个零件需要加工几个设计特征，每个设计特征需要加工几个制造操作。建立或转换时间取决于顺序，而顺序在一定程度上受技术优先约束的限制。几台机器被分组到一个工作站，分配给它的操作需要最少的设置或转换时间。问题是制定一个机器分组、排序、刀具分配和选择切割条件的计划。

Integrated Machine Grouping, Tool Allocation, and Sequencing in Line DesignThis research program provides an important support function to manufacturing process planning. In recent years, many manufacturers have made a significant investment to record the best manufacturing practices. The resulting databases and knowledge-bases give a good opportunity to offer an automation capability which can be materialized through a rigorous understanding of the process planning problem. The manufacturers will get a competitive advantage through the development of mathematical models and algorithms for automation and validation with industrial data. The proposal considers a high volume production of a complex part, which is produced in a transfer line. Here, machines are flexible and capable of performing all planned operations at a controllable speed. The capability of a machine is different when allocated with a different set of tools in its tool magazine. Each part requires machining of several design features and each design feature requires machining of several manufacturing operations. Set-up or changeover time depends on the sequence which is partly restricted by technological precedence constraints. Several machines are grouped into a workstation, which is assigned with operations that require a minimal set-up or changeover time. The problem is to develop a plan for machine grouping, sequencing, cutting tool allocation, and selection of cutting condition.
