ABSTRACT:
A milling method is provided for the manufacture of components composed of difficult-to-cut materials for turbomachines, aircraft and spacecraft by producing recesses with one or more side walls. An end milling cutter which cuts at the circumference and at the tip and has a tip contour which is rounded towards the circumference is used as the rotating milling tool. In addition to rotation about its axis, the milling tool performs an eccentric orbiting motion about an orbital axis spaced apart from its axis. The opposite senses of rotation lead to downcut milling, and the orbital axis performs a translational advance motion on a straight and/or curved path transversely to its longitudinal direction, with or without a swivelling motion.
