切削液用量的合理控制是减少切削液消耗的重要途径。在切削原理没有发生根本性改进的情况下,通过使用适量的切削液和工艺参数协调加工过程,降低切削液用量,是实施绿色加工的重要手段。以加工过程中机床设备的性能约束为前提,以切削三要素和切削液流量为优化变量,建立了以成本、切削液用量为优化目标的面向绿色制造的少切削液加工工艺参数多目标优化模型,提出了将多目标优化问题和约束转换为单目标优化的方法,并利用遗传算法对该单目标优化函数进行了优化求解。案例分析验证了所建模型的有效性。
Reasonable control of cutting fluid is an important way to reduce the antount of cutting fluid consumption. Without radical improvement of cutting theory, appropriate use of cutting fluid with process parameters for machining process coordination to reduce the amount of cutting fluid is an important means of implementing green machining. After considering machine tool property constraints,a multi-objective optimization model for green manufacturing is established, which takes the three elements of machining and cutting fluid flow as the optimization variables, the processing cost and dosage of cutting fluids as the optimization objectives. The linear-weighted summation method is utilized to transform the multi-objective optimal model into a single criterion optimization model and a hybrid genetic algorithm (GA) is applied to solve it. To assess the effectiveness of the multi-objective optimization model, a case study is utilized to verify the effectiveness of this model.
