五轴球头铣刀铣削力的预测是一个相当大的挑战，由于难以确定未成形的切屑厚度和啮合切削刃。为了解决这些问题，本文提出了一种新的机械模型的基础上，刀具运动分析的切削力。在该模型中，为确定未变形切屑厚度，首先建立了曲面五轴球头铣刀铣削过程中切削刃扫掠曲面的解析模型。根据连续改变刀轴方向时切削刃的真实的运动轨迹，计算出未变形切屑厚度。采用Z图法对啮合切削刃进行了验证，并对切削系数进行了标定。采用力学方法预测切削力。在不同的刀具姿态和切削条件下进行了验证试验。预测值和实测值之间的比较表明，建议的切削力预测模型的适用性。
The prediction of five-axis ball-end milling forces is quite a challenge due to difficulties of determining the underformed chip thickness and engaged cutting edge. To solve these concerns, this paper presents a new mechanistic model of cutting forces based on tool motion analysis. In the model, for undeformed chip thickness determination, an analytical model is first established to describe the sweep surface of cutting edge during the five-axis ball-end milling process of curved geometries. The undeformed chip thickness is then calculated according to the real kinematic trajectory of cutting edges under continuous change of the cutter axis orientation. A Z-map method is used to verify the engaged cutting edge and cutting coefficients are subsequently calibrated. The mechanistic method is applied to predict the cutting force. Validation tests are conducted under different cutter postures and cutting conditions. The comparison between predicted and measured values demonstrates the applicability of the proposed prediction model of cutting forces.
