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.

9300835 Dutta 这项研究的目标是弥补计算机辅助工艺规划和计算机辅助制造（计算机集成制造系统中的两个重要组成部分）之间日益扩大的差距。 特别是，它开发了一种计算机辅助工艺规划系统，可以为并行机器上的加工操作生成工艺计划。 在这些下一代数控 (NC) 机床上，多个刀具可以同时加工单个工件，并且可以同时加工多个工件。 最重要的是，在此类机器上，工件可以在一次设置中完全完成，从而缩短循环时间并显着证明公差。 该项目包括一个新颖的概念，即自动拆卸以生成加工序列并最大化并行性。 研究结果将对未来计算机集成制造系统的能力产生积极影响，使它们能够包含并行机床。
