在轨道钻削中，刀具（特殊立铣刀）相对于工件在螺旋轨道上移动。由于三维刀具路径和叠加的旋转切削运动，导致复杂的加工运动，其确定刀具的接触条件。本研究的目的是数学上描述发生的切削条件作为一个功能的技术参数：孔径，刀具直径和梯度的螺旋课程的啮合角。在此数学描述的基础上，可以确定关于轨道钻削过程的进一步基本和定性陈述。理论描述证实了从钻削到铣削的切削特性随刀具的穿透啮合角的变化。
In orbital drilling the tool (special end mill) moves relative to the work piece on a helical course. Because of the three-dimensional tool path and the superimposed rotary cutting motion a complex machining motion results which determines the contact conditions of the tool. The objective of this study is to describe mathematically the occurring cutting conditions over the engagement angle as a function of the technology parameters: bore diameter, tool diameter and the gradient of the helical course. On the basis of this mathematical description further fundamental and qualitative statements regarding the cutting process of orbital drilling can be determined. The theoretical description confirmed a change of the cutting characteristic over the penetration engagement angle of the tool from drilling to milling.
