Intelligent computer-automated methodologies for manufacturing planning and welded assembly engineering

该研究计划的总体目标是在制造领域的两个方面提出创造性的解决方案，这与航空工业非常相关。项目A：复杂棱柱体零件加工智能化CAPP方法研究的目的是开发一种智能化的计算机辅助工艺设计系统（CAPP）。基于软计算技术应用的方法，用于自动化加工操作选择和不同的设置规划任务，以及对所生成的用于加工复杂棱柱形部件的设置计划进行多目标优化。使用的技术，如神经网络，模糊逻辑和遗传算法将进行调查。此外，还将开发方法和软件系统，以便从CATIA CAD数据库中自动提取工艺规划所需的数据。确定薄板搅拌摩擦焊的残余应力，以减少翘曲和变形我们建议使用各种基于计算机的方法，分析研究薄板，通常是铝，然后通过实验验证这些结果。我们的目的是更好地了解如何调整某些工艺参数（如压紧力和刀具运动）以减少板材翘曲。

The overall objective of this research program is to propose creative solutions in two aspects in the area of manufacturing, that are very pertinent to the aeronautical industry.PROJECT A : Intelligent CAPP Methodology for Machining Complex Prismatic ComponentsThe objective here is to develop an intelligent Computer-Aided Process Planning (CAPP) methodology based on application of Soft Computing techniques for automating the machining operations selection and different setup planning tasks, and multi objective optimization of the generated setup plan for machining complex prismatic components. Use of techniques such as neural networks, fuzzy logic and genetic algorithms will be investigated. In addition, the methodology and software system will be developed to automatically extract the data necessary for process planning from the CATIA CAD database.PROJECT B: Determining Residual Stresses in Thin Sheets Welded by Friction Stir Welding to Minimize Warping and DeformationWe propose to analytically investigate, using various computer-based methods, the residual stresses in thin sheets, usually of Aluminium, and then to experimentally verify these results. Our aim is to better understand how certain process parameters (such as the hold-down force and the tool movement) can be adjusted to reduce sheet warpage.
