中文摘要：针对硬质合金刀具高速内冷铣削AISI304不锈钢时,切削力大、切削温度高及加工表面质量低的问题。基于响应曲面中心复合设计方法进行高速内冷铣削实验,建立了铣削力分量二阶回归预测模型,并进行了实验验证。对比了干式与内冷铣削后的加工表面质量,分析了铣削参数对铣削力分量的影响规律,以铣削力分量最小为目标优化了铣削参数。结果表明:进给力和径向力的预测值与实验值的误差分别为4.77%和6.16%;内冷铣削的Ra为0.193~0.327μm;对铣削力分量的影响是铣削深度>转速>进给量,随着铣削深度和转速的增加,进给力先升高后降低,径向力逐步增加,铣削深度与转速的交互作用对进给力和径向力的影响显著;转速11643.63 r/min、铣削深度1 mm、进给量0.08 mm/r为最优铣削参数组合。

外文摘要：Aiming at the problems of high cutting force,high cutting temperature and low surface quality when carbide tool was used to milling AISI304 stainless steel with high speed internal cooling.Based on the response surface center composite test design method,the high-speed internal cooling milling test was carried out,and the second-order regression forecast model of each milling force component was established and verified by experiments.The surface quality after dry milling and internal cooling milling was compared.The influence of milling parameters on the milling force components was analyzed,and the milling parameters were optimized with minimum milling force components as the goal.The results indicate that the error between the predicted value and the experimental value of the feed force and the radial force are 4.77% and 6.16%,respectively.The Ra value of internal cooling milling is 0.193 to 0.327μm.The influence on milling components is milling depth>rotation speed>feed rate,the feed force first increases and then decreases with increasing milling depth and speed,the radial force increases gradually,the interaction between milling depth and speed have a significant influence on feed force and radial force.The optimal milling parameter combination are that speed is 11643.63 r/min,milling depth is 1 mm,and feed rate is 0.08 mm/r.
