中文摘要：
数控加工是目前机械制造系统广泛采用的一种加工方法,为实现数控加工的低碳化,研究数控车削加工的高效低碳切削参数优化问题。建立切削加工过程时间目标函数和包含电能碳排放、刀具碳排放、切削液碳排放的碳排放目标函数。然后,考虑加工过程中机床设备性能和加工质量的实际约束条件,建立以数控加工的切削速度和进给量为优化变量,以最小加工时间（高效）和最低碳排放（低碳）为优化目标的多目标优化模型。引入权重系数将其转化单目标优化模型,并应用复合形法对优化模型进行优化求解。通过某具体实例验证了所建模型的有效性,并对优化结果和优化变量的灵敏度进行了分析。
英文摘要：
The NC machining is a widely used processing method in the mechanical manufacturing system. In order to realize the low carbon of the NC machining, the NC turning parameters optimization problem for high efficiency and low carbon is studied. The processing time objective function and carbon emissions objective function including electric power carbon emissions, cutting tool carbon emissions, cutting fluid carbon emissions are established. Considering the machine tool property and processing quality constraints, a multi-objective optimization model is established, which takes the NC machining cutting speed and feed as the variables, the minimum processing time and the lowest carbon emission as the optimization objectives. The weight coefficients are introduced to transform it into a single objective optimization model and the complex method is applied to solve it. An experiment case is performed to verify the effectiveness of the optimization model, and the machining parameters optimization results and the sensitivity of optimization variables are analyzed.
