Abstract

This paper presents a new method for the detection and elimination of global interference in five-axis machining of sculptured surfaces. Projecting points on the surface to the axis of cutter, the minimum distance from surface to cutter axis can be directly calculated by an iterative algorithm; the amount of interference is subsequently determined. A corrective method for generating an interferential-free cutter location is then proposed. The implementation has proved that the proposed method has a high efficiency and precision.
