项目摘要

In this research, basic structure of integrated CAM system for FMS(Flexible Manufacturing System)has been investigated, and a hierarchical CAM system for the FMS was developed, and some examples were demonstrated.Until now, we do not have an integrated CAM system which is able to carry out the automatic determinations of machining sequence, selection of cutting tool, NC data generation, job allocation for each machining station and scheduling under processing the given geometric model and machining knowledge.At first, in order to develope the integrated CAM system, a detail process of maschining was investigated, and a cell constructed geometric model(CCM) as a geometric model which is able to play a role of interface between CAD and CAM systems, was proposed. And conversion procedure from the CCM solid model to a surface model which consists of some partial machinable surfaces was also proposed.MAchining process is seemed as the time series and aqumulated operation, on the contrary, process planning is also seemed as the inverse reasoning process which generates the serious partial machining surfaces from the given geometric model and machining knowledge.The proposed hierachical CAM system makes it possible to classify the hole, 2-D contouring surface, 3-D sufaces, and to determine the using cutting tools and generation NC data in an interactive way.Finally, some processing results which are processed by the proposed integrated CAM system, are demonstrated.

本研究研究了FMS（柔性制造系统）集成CAM系统的基本结构，开发了用于FMS的分层CAM系统，并演示了一些实例。到目前为止，我们还没有一个集成CAM系统能够在处理给定的几何模型和加工知识的情况下自动确定加工顺序、选择刀具、生成NC数据、每个加工站的作业分配和调度。首先，为了开发集成CAM系统，研究了机械加工的详细过程，并提出了单元构造几何模型（CCM）作为能够在CAD和CAM系统之间发挥接口作用的几何模型。并且还提出了从CCM实体模型到由一些部分可加工表面组成的表面模型的转换程序。加工过程被视为时间序列和累积操作，相反，工艺规划也被视为逆推理过程，从给定的几何模型和加工知识生成严重的部分加工表面。所提出的分层CAM系统使得孔分类、二维轮廓成为可能曲面、3D 曲面，并以交互方式确定使用切削刀具和生成 NC 数据。最后，演示了由所提出的集成 CAM 系统处理的一些处理结果。
