This research project seeks to develop a novel reference-free part encapsulation fixturing technology by extending and further developing the existing phase-change based fixturing technologies. Several key research issues are addressed for successful development and implementation of this new fixturing technology. First, analyses and experiments will be performed for a better understanding of the mechanical and metallurgical behavior of the filler block which fixes the part. Second, technologies for dispensing the filler material, controlling temperatures in casting and handling the filler block will be developed. Third, the developed technologies will be assembled for automating the machining of general three-dimensional components that require multiple setups. The reference-free part encapsulation technology presents some novelty. There exist many fundamental research issues which need to be addressed before this technology can be successfully adopted by industry. This investigation will address these fundamental issues in the development of this technology.

本研究旨在发展一种新的无基准零件封装装夹技术，通过扩展和进一步发展现有的相变为基础的装夹技术。 几个关键的研究问题，解决成功的开发和实施这种新的夹具技术。 首先，将进行分析和实验，以更好地了解固定零件的填充块的机械和冶金行为。 其次，将开发用于分配填充材料、控制铸造温度和处理填充块的技术。 第三，开发的技术将用于自动化加工需要多个设置的一般三维部件。 无基准零件封装技术具有一定的新奇。 在这项技术被工业界成功采用之前，有许多基础研究问题需要解决。 这项研究将解决这项技术发展中的这些基本问题。
