Abstract (en)
[origin: EP2119533A1] The method involves accelerating a milling head (4.1), and accelerating a milling cutter (4) and/or a workpiece spindle (3) in a direction of movement axis (T) in speed. The head and the spindle are drawn near in a direction of the axis with the speed till a distance between the head and a rotational axis (R) of a spindle axle (3.1) is equal to a specific value. The head and the spindle are drawn near with another speed till the distance is equal to another specific value. The latter speed is lowered around 10 percentage at the distance equal to the latter specific value.
