【摘要】：为了实现车削加工过程的低碳化并提高加工质量,在分析车削加工过程中能耗特征及切削温度与刀具几何参数之间关系的基础上,以刀具前角和主偏角为优化变量,考虑加工过程机床设备和加工质量等约束,建立了车削加工刀具几何参数低碳优化模型;针对所建模型,提出一种基于改进的自适应遗传算法的优化求解方法。实例分析表明,以低碳排放为优化目标、以切削温度为约束条件优化车削刀具几何参数,可使碳排放和切削温度比原刀具参数分别降低12%和17%。所建模型和方法可为制造企业优化选择刀具几何参数降低碳排放提供理论方法支持。
[Abstract]:In order to realize the low carbonation of turning process and improve the machining quality, on the basis of analyzing the characteristics of energy consumption and the relationship between cutting temperature and tool geometric parameters in turning process, taking the front angle and main deflection angle of cutting tool as optimization variables, considering the constraints of machine tool equipment and machining quality, a low carbon optimization model of geometric parameters of turning tool is established. Aiming at the model, an optimal solution method based on improved adaptive genetic algorithm is proposed. The example analysis shows that the carbon emission and cutting temperature can be reduced by 12% and 17%, respectively, by taking low carbon emission as the optimization goal and cutting temperature as the constraint condition to optimize the geometric parameters of turning tools. The model and method can provide theoretical support for manufacturing enterprises to optimize the selection of tool geometric parameters to reduce carbon emissions.
