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 tool life for hardened steel SKD1 1 during the mil ing process,the related mil ing experiments are carried out and the influence of cutting parameters on tool life is analyzed based on range method.It is found that the influence of axial cutting depth on tool wear is pretty strong,and the influence of radial cutting width on tool wear is very weak.Based on the mil ing experiments,the mathematical model of tool wear is established by using of regression a-nalysis method.In order to solve the actual mil ing problem,the cutting parameters are optimized by using of SQP optimization method based on MATLAB software.During the optimization process,the machining efficiency and the tool wear quantity are set as the objective function. The optimized cutting parameters could greatly improve the machining efficiency in the premise of ensuring smal er tool wear,and it provides the important theory evidence and case reference for NC machining enterprises to reduce compositive production costs.
