球头铣刀铣削过程模型在CAD/CAM或CAPP系统中的应用需要一种通用的方法来确定不同切削条件下的切削力系数。在本文中，我们提出了一个机械切削力模型的三维球头铣削瞬时切削力系数是独立的切削条件。三维切削的未切屑厚度模型考虑了刀具偏转和跳动。深入分析这些切削力系数的特点，可以确定从只有几个测试切割，提供。为了更准确地预测切削力，尺寸效应也使用球头立铣刀的刀刃长度建模，并被纳入切削力模型。这种方法估计的三维球头铣削力系数进行了实验测试，为各种切削条件。
Application of a ball-end milling process model to a CAD/CAM or CAPP system requires a generalized methodology to determine the cutting force coefficients for different cutting conditions. In this paper, we propose a mechanistic cutting force model for 3D ball-end milling using instantaneous cutting force coefficients that are independent of the cutting conditions. The uncut chip thickness model for three-dimensional machining considers cutter deflection and runout. An in-depth analysis of the characteristics of these cutting force coefficients, which can be determined from only a few test cuts, is provided. For more accurate cutting force predictions, the size effect is also modeled using the cutter edge length of the ball-end mill and is incorporated into the cutting force model. This method of estimating the 3D ball-end milling force coefficients has been tested experimentally for various cutting conditions.
