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

生产线设计中的集成机床配置、刀具分配和排序 该研究项目为制造工艺规划提供了重要的支持作用。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，提供一个自动化的能力，可以通过严格理解的过程规划问题实现。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。 该提案考虑了复杂部件的大批量生产，该复杂部件在转移线中生产。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。在刀具杂志中分配不同刀具组时，机器的能力不同。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。设置或转换时间取决于顺序，而顺序部分地受到技术优先约束的限制。几台机器被分组到一个工作站，这是分配给操作，需要最小的设置或转换时间。问题是制定一个计划，机床分组，排序，刀具分配，选择切削条件。

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