摘　　要：为了研究硬质合金立铣刀磨损寿命与切削参数的关系,基于二次回归法建立刀具磨损寿命与切削参数的数学模型,用F检验法分析模型的拟合程度。通过正交试验法设计铣削模拟方案,用Deform3D软件进行仿真实验,并用MATLAB求解模型系数。为了提高刀具寿命,基于立铣刀磨损寿命模型建立切削参数优化模型,对切削参数进行优化,并对优化结果进行反向试验。实验结果表明优化模型可以对影响立铣刀寿命的切削参数进行优化。On analyzing the relationship of carbide cutting tool life and cutting parameter, firstly, based on the two regression method we can establish the mathematical model about the cutting tool life and cutting parameters and with F in- spection the model of fitting degree can be analyzed. Then by means of the orthogonal designs of regression milling simula- tion schemes, we can use the simulation software Deform3 D to establish a model of milling and use MATLAB to solve mod- el coefficients. After that, in order to improve the life of cutter, based on the model of tool life, the model of parameter op- timization can be set up and the cutting parameters can be optimized. Finally, the optimization results were verified by the reverse experiment. The experimental results show that the model of parameter optimization can be optimized by the cutting parameters of the affecting tool life.
