This research is to develop a scientific basis for analyzing and optimizing fixture configurations in a manner that allows for the automated design of fixtures during computer aided process planning. The uniqueness of the approach is the inclusion of clamping force and the resulting deformation into the optimization process. This will be accomplished by abstracting the workpiece geometry into a finite element model of the part and fixture to analyze both the components as they are subjected to clamping forces. The final stage will be the optimization of the configuration of the fixture on the basis of an optimization model that is to be researched and developed as part of this project. Designing of fixtures to hold the workpiece during processing is a critical aspect of process planning and a function that is still carried out on an empirical basis. A scientific approach will enable the automation of this process while improving the efficiency of the manufacturing sector.

本研究旨在为分析和研究我国的环境污染问题提供科学依据 并以允许以下方式优化夹具配置： 计算机辅助工艺中夹具的自动设计 规划 该方法的独特之处在于， 夹紧力和由此产生的变形量进行优化 过程 这将通过抽象工件来实现 几何形状转化为零件和夹具的有限元模型， 分析这两个组件，因为它们受到夹紧 力. 最后一个阶段将是优化 基于优化模型的夹具配置 作为这个项目的一部分进行研究和开发。 加工过程中夹持工件的夹具设计 是工艺规划的一个重要方面， 仍然是在经验的基础上进行的。 科学的方法 将实现这一过程的自动化，同时提高 制造业的效率。
