【 摘 要 】

The purpose of this paper is to develop a method to determine cutting force components for milling tough materials in different cutting conditions: VT23 titanium grade, 40HN2MA (4340 US Grade) and V95 of high tough aluminium grade. The basis of the method is calculation of the exponential function based on determination of instantaneous values of chip thickness depending on the angle position of the cutting edge. Several tests are used for determination of experimental cutting force for the milling process with tungsten carbide inserts of various geometry in different cutting conditions using industrial equipment, instruments and tooling. The method shows a good convergence with experimental data. It provides an accurate description of cutting force which is enough to determine some phenomenon of cutting force dynamics for these materials. Phenomena of Fx cutting force delay for milling of titanium grade are presented as an example. The nature of the cutting force component delay during the run-off from the single cut may be a case of future study.
