9300835 Dutta本研究的目的是弥补计算机辅助工艺规划和计算机辅助制造之间日益增长的差距，这是计算机集成制造系统中的两个重要组成部分。特别地，它开发了一个计算机辅助工艺规划系统，该系统为并联机床的加工操作生成工艺计划。在这些新一代数控机床上，多个刀具可以同时加工单个工件，多个工件可以同时加工。最重要的是，在这样的机器上，工件可以在一次安装中完全完成，从而缩短了周期时间并显着证明了公差。该项目包括一个新颖的概念，即自动拆卸，以产生加工序列和最大化的并行性。研究结果将积极影响未来计算机集成制造系统的能力，使它们能够包括并行机床。

9300835 Dutta The goal of this research is to remedy the growing disparity between computer aided process planning and computer aided manufacturing, the two vital components in a computer integrated manufacturing system. In particular it develops a computer aided process planning system that generates process plans for machining operations on parallel machines. On these next generation numerically controlled (NC) machines, multiple tools can simultaneously machine a single workpiece and multiple workpieces can be machined simultaneously. Most importantly, on such machines a workpiece can be completely finished in a single setup, resulting in shorter cycle times and significantly i proved tolerances. This project includes a novel concept, that of automatic disassembly to generate machining sequences and maximize parallelism. Results of the research will positively impact the capabilities of future computer integrated manufacturing systems by enabling them to include parallel machine tools.
