本文提出了一种面向端面加工的自动工艺规划系统，该系统考虑了CAM操作员的工艺规划意图。在以前的工艺设计系统中，加工顺序是基于总去除体积(TRV)和从TRV分割出的加工区域来几何计算的。然而，从大量计算的加工序列中确定最佳加工序列仍然是困难的。以前的工艺规划系统在确定适当的加工顺序时也不考虑CAM操作员的意图。首先，当CAM操作员决定加工顺序时，我们的新工艺规划系统存储加工特征的优先级和所选加工区域的几何属性。在存储加工特征的优先级和几何属性后，可以通过参考这些信息来自动确定合适的加工顺序。凸轮操作员的意图隐含在加工区域存储的几何属性中，可用于确定加工顺序。通过实例研究，验证了本文提出的新工艺设计系统的有效性。在实例研究中，基于加工区域的几何属性和单个CAM操作员意图之间的隐含关系，自动确定用户特定的加工序列。
In this study, an automatic process planning system for end-milling operation is proposed, in which CAM operator’s intention for process planning is considered. In the previous process planning systems, the machining sequence is calculated geometrically, based on the Total Removal Volume (TRV) and the machining region split from TRV. However, it remains difficult to determine the best machining sequence from the large number of the calculated machining sequences. The previous process planning systems also do not consider CAM operator’s intention in the determination of the appropriate machining sequence. First, our new process planning system stores the priority of machining feature and the geometrical properties of the selected machining region when a CAM operator decides the machining sequence. After storing the priority of machining feature and the geometrical properties, the appropriate machining sequence can be automatically determined by referring this information. CAM operator’s intention, which is involved implicitly in the stored geometrical properties of the machining region, can be applied to decide machining sequence. A case study was conducted to show the effectiveness of our new proposed process planning system. In the case study, user-specific machining sequences were automatically determined based on the implicit relation among the geometrical properties of the machining region and the individual CAM operator’s intention.
