摘要
为了充分考虑切削加工参数优化中的不确定性问题,该文提出了一种适用于TC4钛合金高速铣削参数优化的“非确定性的”模型,即模糊正交优化模型。该模型以切削力恒定和较高的金属去除率的模糊综合值作为目标函数,找出了最佳切削用量。实验和仿真表明:该模型得到的最佳切削用量与实验的分析结果和生产现场的经验分析结果一致性好。该模型实用性强、精度高、易于编程,对于指导实际生产、实现智能加工具有重要意义。
In order to consider the problems of uncertainness in the optimization of cutting parameters, this paper presents a “uncertain” model named fuzzy orthogonal optimization, which is applied to the optimization of cutting parameters for high-speed milling titanium alloy TC4. In this model, the fuzzy comprehensive evaluation of the fixed milling force and higher metal removing rates is used as the objective function so that the best cutting parameters are gotten. The experimental simulation shows that the best cutting parameters gotten from the model are in good consistency with the cutting parameters gotten from the experiments and in practical manufacturing. This model is practical, accurate and easy to guide progratmning and to realize intelligent machining.
