【摘要】 根据插铣核电材料A508-3钢各向最大切削力的正交实验数据,建立插铣过程的切削参数(切削速度、每齿进给量和径向切削宽度)各向最大切削力预测模型。把切削力预测值与实验值的残差平方和为适合度函数,采用谢菲尔大学研究的遗传算法工具箱实现各向最大切削力预测模型的各项参数。结果表明切削力预测模型与实验值吻合较好。本文目的是在特定插铣切削参数条件下预测切削力。更多还原

【Abstract】 Based on the plunge milling nuclear material A508- 3 steel experimental results of the maximum cutting force,a predictive model with cutting parameters( cutting speed,feed per tooth and radial cutting width) is established. The residual sum of squares( RSS) is takes as fitness function. Force prediction and experimental forces of the residual sum of squares( RSS) takes as the fitness function,genetic algorithm toolbox sheffield university is used to study the maximum cutting force prediction model parameters of plunge milling. The results showed that the cutting force prediction model is in good agreement with the experimental values. The purpose of this paper is to predict the cutting force in the cutting parameters under the particular conditions of the plunge milling.更多还原
