摘要
以螺旋立铣刀为研究对象,通过对铣削过程的理论分析,建立实验测量值与瞬时铣削力之间的几何关系,并通过全铣削过程简化模型,得出最终瞬时铣削力模型。采用碳纤维复合材料实验测得的平均铣削力对铣削力模型进行逆向求解,求出了四种纤维方向下的铣削力系数,根据铣削力预测模型对铣削力进行预测,并与实际测量值进行比较,最大误差为9.18%,模型预测结果较准确。
This paper selects the spiral end mill as the research object,carries out the theoretical analysis of the milling process,establishes the geometric relationship between the experimental measurement value and the instantaneous milling force.The model is simplified through the entire milling process,and the final instantaneous milling force model is obtained.The average milling force measured by the carbon fiber composite material experiment is used to reverse the milling force model,and the milling force coefficients in the four fiber directions are obtained.By predictive model of milling force the milling force is predicted and be compared with the actual measured value.The maximum error is 9.18%,and the model prediction result is more accurate.
