Engineering Faculty Internship: Development of Low Cost Precision Investment Casting Process with 97-100% Recovery of Good Products

飞机发动机的设计和制造是复杂的。在这个项目中，并行工程方法将作为团队建设的工具，用于飞机发动机零件的精密熔模铸造设计和制造。设计和制造的概念被整合为一个完整的系统，涉及计算机集成制造(CIM)、使用田口方法和质量功能展开(QDF)的全面质量控制(TQC)以及准时(JIT)生产技术等最先进技术的同时(同时)应用。设计/制造总体系统的概念表明，成本和质量并不是生产企业的对立面。飞机发动机的设计和制造操作虽然复杂，但可以高质量和低成本地进行，使用并行工程产生的整个系统概念作为团队建设工具。在这项研究项目中，飞机发动机的一些主要部件将通过应用设计/制造全系统方法学通过精密熔模铸造来制造。

The design and manufacture of aircraft engines are complex. In this project, the concurrent engineering methodology will be used as a team-building tool for the design and manufacture of some aircraft engine parts by precision investment casting. The concepts of design and manufacturing are integrated as a total system involving the concurrent (simultaneous) application of such state-of-the-art techniques as computer integrated manufacturing (CIM); total quality control (TQC) using Taguchi methods and quality function deployment (QDF); and just-in-time (JIT) production techniques. The design/manufacturing total system concept shows that cost and quality do not lie at the opposite spectrum of the production enterprise. The design and manufacturing operation of aircraft engines, though complex, could be performed at high- quality and at low-cost using the total system concept derived from concurrent engineering as a team-building tool. In this research project, some major components of an aircraft engine are to be manufactured through the application of the design/manufacturing total system methodology by precision investment casting.
