Abstract

The objective of this paper is to present a new adaptive spiral cutting method and its implementation in CAD/CAM software applications. A Visual Basic (VB) macro automatically generates a spiral tool path for the machining of pockets in aircraft wing components. The second part of the paper is aimed at improving the cutting methods for machining pockets with inclined walls. During the roughing operation, the proposed tool path takes into consideration the slant of the walls but also allows maximizing the quantity of material to be removed.
