This paper presents a study of the relationship between cutting force and tool crater wear of solid carbide tool during milling Ti6Al4V. The cutting force model in milling considering tool crater wear is discussed, which shows that for given the cutting conditions, tool geometries, and workpiece material, cutting force under the tool crater wear effect could be predicted easily and conveniently. The tool wear condition in milling Ti6Al4V is obtained by finite element simulation method. In addition, the experimental work of end milling Ti6Al4V with solid carbide tool is developed. Comparisons among experiment results, mathematical model results, and finite element simulation model results, including cutting force and tool wear, are discussed. The results show that the proposed mathematical model could predict cutting force under the tool crater wear effect with higher accuracy.

本文研究了硬质合金刀具铣削Ti6Al4V时切削力与刀具弹坑磨损之间的关系。讨论了考虑刀口磨损的铣削切削力模型，结果表明，在给定切削条件，刀具几何形状和工件材料的情况下，刀口磨损效应下的切削力可以轻松，方便地预测。通过有限元模拟方法获得了铣削Ti6Al4V时的刀具磨损条件。此外，还开发了使用整体硬质合金刀具铣削Ti6Al4V的实验工作。讨论了实验结果，数学模型结果和有限元模拟模型结果（包括切削力和刀具磨损）之间的比较。
