提出了一种新的切削力估计模型。它是基于比切削力系数，定义为切屑厚度的函数。所提出的切削力模型的显著特征是在刀具的每个位置上使用平均切屑厚度进行切削力计算，这样只需要在刀具的每个角度位置上进行一次迭代。该模型基于实际的工件-刀具相互作用，提供了有关切削刃实际位置的信息。它为科学文献中通常基于数值积分的其他研究提供了另一种选择。利用该模型，不仅可以估计稳态条件下的切削力，而且可以估计轴向和径向切削深度变加工条件下的切削力。
A new model for cutting force estimation is presented in this paper. It is based on the specific cutting force coefficient, which is defined as a function of chip thickness. The distinguishing feature of the proposed cutting force model is the use of average chip thickness for cutting force calculation on each position of the cutting tool, in such a way that only one iteration is needed on every angular position of the tool. This model is based on the actual workpiece–tool interaction which provides information about the real position of the cutting edge. It provides an alternative to other studies in scientific literature commonly based on numerical integrations. With this model, it is possible to estimate the cutting forces not only under steady-state conditions but also under variable machining conditions of axial and radial depth of cut.
