Research Initiation: Automatic Design of Machining Fixturesfor Automatic Process Planning

因为夹具是特殊的工具， 通常用于制造一种类型的部件， 小批量生产的夹具在每个零件上都过多 基础 一个关键的需要是存在的自动化， 自动化加工中的夹具设计 规划小批量生产。 这个项目是针对 制订综合方法， 以下夹具决策：概念设计， 所需夹具，每个夹具中的工件方向，夹具 点和夹紧力。 该方法将基于 工程力学和夹具中使用的声音原理 实践 前者用于确保正确的设计， 后者被用作夹具综合的高级指导。 在 此外，还讨论了零件几何形状的推理， 为工艺规划的集成提供了基础， 夹具设计 将开发一个原型系统， 知识系统工具。

Because fixtures are special tools in the sense that each is generally used for making one type of parts, the time and cost of fixturing for small-batch production are excessive on a per-part basis. A critical need is shown to exist for automating the design of machining fixtures in the context of automatic process planning for small-batch production. This project is directed towards the development of an integrated methodology for the following fixturing decisions: conceptual design, the number of fixtures needed, workpiece orientation in each fixture, fixturing points and clamping forces. The methodology will be based upon engineering mechanics and sound principles used in fixturing practice. The former is used to ensure proper design and the latter is used as high level guidance for fixture synthesis. In addition, the reasoning of part geometry is addressed, which provides a basis for the integration of process planning and fixture design. A prototype system will be developed using knowledge system tools.
