摘要
现代数控铣削加工中,型腔加工是广泛面临的一类加工问题。由于型腔结构的复杂性,需多次更换不同的刀具才能完成对零件的加工。针对此情况可能出现能耗过多的问题,研究提出了一种面向低能耗的刀具最优组合方法。首先,在可用刀具的范围内,建立了以刀具序列为优化对象,以能量消耗为优化目标的优化模型;其次,利用了Dijkstra算法,以最短路径类比于最低能耗,对上述模型进行了求解;最后利用案例验证了所提模型及方法的有效性。该模型为今后研究型腔加工的能耗奠定了一定的基础。
Pocket machining is a widely faced situation in modem NC milling machining. Considering complexity of pocket structure, it need change different tools to complete parts＇ processing. It is possible to waste excessive energy with machining method. So a optimal tool combination method for low energy consumption is proposed. First, in the range of available tools, an optimization model is established with the tool sequence as the optimization object and the energy consumption as the optmizafion target. Second, the Dijkstra algorithm is used to solve the above model by comparing the shortest path to the lowest energy consumption. Finally, the effectiveness of the proposed model and method is verified by a case study. The model can provide some certain foundation for studying energy consumption of pocket milling in the future.
