Abstract
A procedure to machine openings in work pieces which provides two cutting blades ( ), defining a cutting blade axis, adjacent to a work piece in which an opening is to be machined, the opening defining a distance between two oppositely positioned opening edges and defining an opening axis. The opening axis and the cutting blade axis are inclined at an acute angle (&agr;) to one another in a way that the distance between the cutting blades parallel to the opening axis ( ) is equal to the required distance between the opening edges. With the increasing wear of the cutting blades, the inclination angle is reduced so that the cutting blade distance parallel to the opening axis continues to correspond to the required distance of the opening edges.
