为提高SKD11模具钢铣削刀具的寿命,对SKD11模具钢进行了刀具寿命铣削试验,基于极差方法分析了各工艺参数对刀具寿命的影响规律。基于刀具寿命铣削试验,利用多元线性回归方法,推导并求解出了SKD11模具钢铣削刀具磨损的数学模型。利用最优化设计方法和MATLAB优化工具箱,以加工效率和刀具磨损为目标函数,针对实际的铣削问题优选了工艺参数。优化的工艺参数能兼顾刀具寿命和加工效率,为加工企业降低综合生产成本提供了重要的理论依据和案例参考。
In order to improve the service life of SKD11 die steel milling cutter, the tool life milling test of SKD11 die steel was carried out. The influence law of various process parameters on the tool life was analyzed based on the range method. Based on the tool life milling test, the mathematical model of tool wear of SKD11 tool steel was deduced and solved by multivariate linear regression method. Using the optimization design method and MATLAB optimization toolbox, taking the machining efficiency and tool wear as the objective functions, the process parameters are optimized for the actual milling problems. Optimized process parameters take into account the tool life and processing efficiency, processing enterprises to reduce the overall cost of production provides an important theoretical basis and case reference.
