后刀切削可以有效地代替传统的点切削加工直纹面。为了减少设计和加工的扭曲直纹面之间的差异，建立了一个分析模型来解释圆柱刀具在侧切加工中产生的根切。基于该模型，观察了刀具的扭角、刻划长度和所用刀具的尺寸与根切的大小之间的关系。以某型五轴机床为例，以叶轮扭曲直纹叶片型面的侧切加工为例，说明了所开发的五轴侧切加工技术。
Flank cutting can be effectively employed to machine ruled surfaces instead of traditional point cutting. In consideration of reducing discrepancies between designed and machined twisted ruled surfaces, an analytical model is established to account for undercutting incurred in flank milling by the use of cylindrical cutters. Based on the model, the twist angle, the ruling length, and the size of the used cutter relating to the magnitude of undercutting are observed. By flank milling twisted ruled blade surfaces of an impeller, an application example is given to show the developed 5-axis flank milling technique based on a type of a 5-axis machine tool.
