Study on cutting parameters optimization model for NC turning process based on carbon benefit

为了降低数控车削的加工成本和加工过程中的碳排放量,在分析加工成本和碳排放量与车削切削参数关系的基础上,建立了数控车削加工过程的成本估算函数和碳源特性函数,以机床的主轴转速、进给量和背吃刀量作为优化变量,考虑机床性能参数和加工质量等约束,提出碳效益这一评价指标,建立了基于碳效益的数控车削切削参数优化模型,并通过一个示例,运用遗传算法对模型进行了求解,验证了该模型的有效性。

In order to reduce the cost of NC turning and carbon emissions in the turning machining process, based on the analysis of the relationship among carbon emissions, cost of NC turning and turning cutting parameters, the carbon source characteristic function and cost estimating function are established. Then taking the machine tool spindle speed, feed and cutting depth as the optimization variables, considering the machine property parameters and processing quality constraints, puts forward the carbon benefit evaluation indicator, and establishes the optimization model of turning parameters based on carbon benefit. The model is demonstrated by using an example part. And genetic algorithm is employed.
