Preloading milling tools - only for G code program (CYCLE800)

After "Swivel plane", the tool orientation is always perpendicular on the machining plane.
When milling with radial cutters, it can make technological sense to set the tool at an angle
to the normal surface vector. In the swivel cycle, the setting angle is generated by an axis
rotation (max. +/- 90 degrees) to the active swivel plane. When setting, the swivel plane is
always "additive". With "Setting tool", only rotations are displayed on the swivel cycle input
screen form. The user can freely select the rotation sequence.

The length up to the TCP (Tool Center Point) must be entered as tool length of the radial
