摘要：
In this paper, the contribution of tool wear to friction was determined for precision hard turning using Cubic Borone Nitride (CBN) cutting tools. The tool nose wear VBC and the corresponding changes of component forces Fc, Ff, and Fp resulting from tool wear evolution were continuously measured during wear tests. Based on the mechanics of nonorthogonal cutting, the normal and friction forces acting on rake and flank faces were calculated for all measuring points, and as a result, relevant changes of the friction coefficient were determined. Additionally, friction changes resulting from tool wear under different feed rate, depth of cut, and tool nose radius were discussed in terms of the plowing energy produced by the tool nose.
