Abstract
The invention concerns a 3D milling machine and a 3D milling process. The milling machine comprises a milling unit ( ) with a motor driven work spindle ( ) for receiving a milling tool, a work table for clamping work pieces, guide and drive device for producing relative movement of the milling unit and the work table in at least three spatial directions, and a laser device ( ) for emitting a laser beam. A laser assisted milling of free-form surfaces is made possible in that the milling unit is a spherical cutter ( ), further, that a mounting device ( ) and a driving device ( ) are provided for producing a precise movement of the laser emitter ( ) about a point on the beam axis, such that the laser beam ( ) circles about a central axis, which intersects the axis of the work spindle ( ) at an acute angle, as well as a mounting device and a driving device for at least one of pivoting and rotating of the work table ( ) about at least one axis.
