摘要
为了提高数控铣削加工过程的能量利用率,降低铣削加工过程中的碳排放量,基于铣削加工能耗分析的基础,建立了数控铣床能耗模型,并基于铣削工艺输入输出特性提出了铣削工艺碳排放评估函数,结合材料去除率提出碳效率概念,以此作为优化目标,并以机床主轴转速和进给量作为优化变量,考虑机床各项性能参数和工件的加工质量等约束,建立了基于碳效率的数控铣削切削参数优化模型,并通过案例,采用遗传算法对模型进行优化求解,验证了该模型的有效性。
In order to improve the energy utilization rate of theCNC milling process and reduce the carbon emission during the milling process,this paper establishes the energy consumption model of the CNC milling machine based on the analysis of the energy consumption of the milling process,and proposes the milling process based on the input and output characteristics of the milling process.The carbon emission assessment function,combined with the material removal rate,proposes the carbon efficiency concept as the optimization target,and based on the spindle speed and feed rate of the machine tool as the optimization variables,considering the constraints of the machine tool performance parameters and the machining quality of the workpiece,the basis is established.The carbon efficiency CNC milling cutting parameter optimization model,and through the case,the genetic algorithm is used to optimize the model,and the validity of the model is verified.
