Abstract
The invention relates to a method for producing a hole in a workpiece consisting of a fibre-reinforced composite material. The central axis of the hole passes through a predetermined point on the surface of the workpiece and is oriented in a certain determined direction in relation to the longitudinal directions of the fibres in the immediate vicinity of the point. The material is machined simultaneously in both an axial and a radial sense by causing the tool to describe an axial motion and to rotate not only about its own axis (5), but also eccentrically about the central axis.
