摘　　要：航空铝合金的高速铣削加工产生了大量的能耗,通过获得铣削加工过程中的铣削力有效值,可以更加准确地预测铣削加工产生的能耗,对于实现绿色制造具有重要的意义。提出一种求解铣削力有效值的方法,通过理论推导建立铣削力有效值关于铣削力系数、铣削深度、每齿进给量之间的函数关系。然后采用瞬时铣削力系数识别方法求出不同切削状态下的铣削力系数,拟合出铣削力系数关于每齿进给量之间的函数关系,计算出相应的铣削力有效值。计算结果表明实测的铣削力有效值与拟合的铣削力系数求解的铣削力有效值在数值和变化趋势上一致性更好。The high speed milling of aeronautical aluminum alloy consumes a lot of energy. The energy consumption of milling can be predicted more accurately by obtaining the effective value of the milling force in the milling process,which is of great significance to the realization of green manufacturing. A method for solving the mean value of milling force is proposed in this paper. It is that the relationship between the effective value of milling force and the relationship between milling force coefficient,milling depth and feed per tooth is established by theoretical deduction. After that the milling force coefficient of different cutting states is obtained by using instantaneous milling force coefficient identification method and the function relation between milling force coefficient and feed per tooth is fitted to calculate the effective force of milling force. The calculation results show that the measured effective force of milling force is in good agreement with the numerical value and trend of milling force effective value calculated by milling force coefficient fitting.
