表面粗糙度在成品零件的性能中起着重要作用。加工操作中产生的表面粗糙度受到大量因素的影响，例如切削参数、切削刀具特性、工件特性或切削现象。球头立铣刀的切削几何特性对表面凸峰的产生有明显的影响。本文研究了球头立铣刀刃口几何特性对理论表面粗糙度的影响。表面上的波峰高度（h）和粗糙度平均参数（Ra）被计算为切削刀具半径（R）和径向切削深度（Ae）的函数。还考虑了表面倾斜度。分析了切削参数对球头铣刀材料去除率的影响。文中给出的计算公式，特别是计算图，可方便地应用于生产实践，以提高球头铣刀的加工质量和生产效率。最后，进行的实验允许观察和量化的理论方法的偏差。
Surface roughness plays an important role in the performance of a finished part. Surface roughness generated in machining operations is influenced by an enormous set of factors such as cutting parameters, cutting tool characteristics, workpiece properties, or cutting phenomena. Cutting geometric characteristics, when ball end mill is used, clearly affect surface crests generated. In this paper, we study the influence of the geometric characteristics of ball end mill cut on the theoretical surface roughness obtained. The crests height on the surface (h) and roughness average parameter (Ra) are calculated as function of cutting tool radius (R) and radial depth of cut (Ae). Surface angularity is also considered. This work also analyzes cutting parameters implication on material removal rate (MRR) of ball end milling operations. The equations and especially the figures presented in this paper can be easily applied in workshops to improve quality and productivity of ball end milling operations. Finally, experimentation carried out permits to observe and quantify the deviations of the theoretical approach.
