Achieving quasi constant machining strip width in five-axis frontal grinding with toroidal tools

摘要

Five-axis frontal grinding has an advantage in finish machining of freeform surface due to high surface accuracy and material removal rate. This article focuses on achieving nearly constant machining strip width with toroidal cutter. To begin with, the initial tool path is generated to realize the maximum machining strip width with fixed yaw angle at each cut contact point and then the verges of machined area convergent to the effective machined area after modifying tool posture. The experimental test shows that the proposed method can obtain quasi constant machining strip width.
