摘要： 从球头铣刀切削过程中能量不变这一机理出发,系统地研究了球头铣刀切削刀的力学性能,并以严格的数学手段推导出一种基于能量法的新型力学模型,以克服目前国内外铣刀力学建模主要依赖于正交切削实验的缺陷.试验结果表明本文所提出的力学模型能精确地预测球头铣刀切削时的三向受力,具有重要的工程实用价值.

关键词: 正交切削, 球头铣刀, 斜角切削, 铣削力

Abstract: According to the principle of power keeping constant in the process of cutting, this paper systematically studies the forces performance of cutting edge of ball-end milling cutter and develops a new forces model based on power by strict mathematical means so as to overcome the fault which results from the fact that forces modeling depends mainly on the orthogonal cutting experiments. The experiment results prove that the model presented in this paper can precisely predict the 3D forces of ball-end milling cutter in cutting, and has important engineering value.

Key words: ball-end milling cutter, milling forces, oblique cutting, orthogonal cutting
