Difference between 3, 3+2 and 5 axes
Pre-positioning of the milling cutter at the workpiece
In the geometry programs, the milling cutter should first be pre-positioned at the workpiece,
because if TRAORI is active, a collision with the workpiece at any given position in the milling
machine's interior or overtraveling of the software limit switch cannot be ruled out during
orientation of the rotary axes. You can define the rotary axis positions either via CYCLE800 or an
ORIRESET.

ORIRESET (90, 45)
By programming ORIRESET (A, B, C), the orientation axes are moved in linear and synchronous
motion from their current position to the specified basic position. ORIRESET is only possible
when TRAORI is active. If a basic position is not programmed for an axis, a defined position from
the associated machine data $MC_TRAFO5_ROT_AX_OFFSET_1/2 is used.
