本研究实现了端面铣削加工的自动化工艺规划系统。本研究认为在工艺规划中应尽量减少换刀次数，并确定合适的加工顺序。在我们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加工条件。首先，新的工艺规划系统生成加工区域关联图，该关联图表示用于确定加工顺序的几何约束。根据关联图，可以从加工序列的众多候选者中选出候选者。随后，我们的新工艺规划系统在考虑加工条件的情况下确定最佳加工顺序。确定了最佳加工顺序，使换刀次数最少。通过实例验证了所提出的工艺规划系统的有效性，并根据工艺规划中考虑的几何约束和操作规划中考虑的加工条件自动确定加工顺序。
In this study, the automated process planning system for end-milling operation is realized. This study considers to minimize the number of times of tool change and to determine the appropriate machining sequence in the process planning. In our previous process planning system, the machining sequence is calculated geometrically, based on the Total Removal Volume (TRV) and the machining regions split from TRV. However, it remains difficulty to determine the best machining sequence from the large number of the calculated machining sequences. The previous process planning systems also do not consider machining conditions in the determination of the appropriate machining sequence. First, our new process planning system generates the association chart of machining regions, which represents the geometrical constraints to determine machining sequence. According to the association chart, the candidates can be selected from the enormous candidates of the machining sequence. Subsequently, our new process planning system determines the best machining sequence under considering the machining conditions. The best machining sequence is determined to minimize the number of times of tool change. A case study was conducted to show the effectiveness of our new proposed process planning system, and the machining sequence was automatically determined based on the geometrical constraints considered in process planning and the machining conditions considered in operation planning.
